"Liv, wake up." Brian gently pushed Olivia's shoulder. "Wake up babe. We have to go soon."

Olivia groaned and looked at the alarm clock. It was 8:13 am. Her first chemotherapy treatment began at ten. She sighed, already dreading it.

Olivia stood up and walked into the bathroom to get herself ready. Brian remained in the bed and rubbed his forehead. He couldn't believe this was happening. Olivia didn't deserve this.

An hour later Olivia and Brian were finishing their breakfast. They ate in silence. Neither of them could talk. It was almost an awkward silence. Just as Olivia was about to stand up, her cell phone started ringing. It was Cragen.

"Cassidy."

"Hey Liv. I just wanted to wish you luck today. You're going to be fine. I can feel it."

"Thanks Captain."

"I also want you to know that if you ever need help or support or anything, I am always here. I'm also positive that the others will be here also. You don't be afraid to ask."

"Thank you. I will ask when I need it. I appreciate it."

Olivia heard a voice in the back. "I got to go Liv. I'll talk to you later."

"okay, bye." Olivia hung up the phone and set it on the table.

Brian looked at her. "Its 9:30. We should probably go."

Olivia nodded and slowly stood up. She wished she could run away from this, but she is sick. She needs treatment.

Brian and Olivia put their coats on and walked out to Brian's car. They silently drove to the hospital.

Once they arrived at the hospital Olivia told the receptionist she was there and she and Brian seated themselves in the waiting room. Brian took Olivia's hand in his and gently squeezed it. Olivia looked over to Brian and sadly smiled. They looked into each other's eyes until the doctor called Olivia's name. Brian and Olivia stood and followed the doctor into a room.

The doctor pointed to a chair and Olivia sat down.

"Ok Olivia. We are going to insert the needle into your arm that will have the chemo." The doctor and the nurse prepared the needle and the chemo.

"Okay, this might hurt." The doctor warned as he found the vein in her arm. Olivia grabbed Brian's hand and squeezed as the needle entered her arm.

"Okay so treatment will last about two hours. You may feel tired or nauseous. There is a pail behind your chair if you need it. Also pillows are over there." The nurse pointed to a cupboard.

Olivia and Brian both nodded. "I'll be back soon to check how it's going." The doctor checked one last time to be sure everything was working properly then left.

Olivia leaned back in the chair, still holding Brian's hand. Brian lifter her hand to his lips and softly kissed it. "You are strong Olivia."

Olivia felt tears filling her eyes. She never thought this would happen to herself. A few tears slid down her cheeks.

"Hey, hey, hey. Don't cry." Brian wiped her tears away. "You are strong. You will beat this."

Olivia sighed. "I sure hope so Brian."

An hour later the doctor came and checked everything and to see how Olivia was doing. She told the doctor all was well. The doctor told her she may feel sick soon and then left again.

No more than ten minutes after the Doctor left Olivia began to feel nauseous.

"Brian."

"Yeah?"

"I need that pail." Olivia threw her hand to her mouth and Brian quickly jumped up and grabbed the pail. Just as he put it under Olivia's mouth she emptied her stomach into it. When she felt she was done she leaned back in the chair moaning.

Brian called the nurse in who took the pail to clean it out.

Brian rubbed Olivia's back and moved the hair out of her face. "You're okay."

"I don't know about that." Olivia sighed and closed her eyes.

The doctor and the nurse came back an hour later and told Olivia she was done for the day. They took the needle out.

"Okay we want you back here in exactly one week. We want to get three treatments in before we check your progress, so every week we will see you for the time being. In the next while you will begin to feel some of the side effects of chemotherapy. This may include nausea, which you've already experienced, fatigue, not wanting to eat and pain where the needle was. There may be more but these are most common."

Olivia cleared her throat. "What about um- h-hair loss?"

The doctor nodded. "That is a side effect but not until a little later in the treatment process."

Olivia nodded; relieved she wouldn't be losing her hair just yet. Brian and Olivia finished speaking with the doctor and left. Brian helped Olivia into the car; she was still quite nauseous and tired.

When they arrived at their apartment Brian helped Olivia get settled in bed and brought a pail in just in case she needed it. He sat with Olivia until she fell asleep.

Brian was cooking supper later that night. He wasn't sure if Olivia would be up to eating later, but he was cooking enough for her anyway. Olivia's cell phone sitting on the table began to ring. Brian picked it up and saw Cragen's name on the screen.

"Hello?" Brian answered.

"Brian? It's Don Cragen."

"Hi Cragen. What do you need?"

"I just wanted to see how Olivia is doing."

"She's asleep right now. She is already sick after just one treatment."

Cragen sighed into the phone. "Do you think she'll be up for visitors tomorrow? I have some detectives here who miss her."

Brian softly chuckled. "Yeah, I think she will be okay with that. She'll be tired but I know she misses you guys too."

"Okay, well we will see you tomorrow then."

"Sounds good, bye." Brian hung up Olivia's cell phone and walked into the bedroom to check on Olivia.

Brian walked in to see Olivia vomiting into the pail beside the bed. Brian rushed over to her and held her hair back and rubbed her back.

Olivia coughed and wiped her mouth, slowly lying back onto the bed.

Brian sat on the edge of the bed and held her hands in his. "Is it okay if your squad comes for a visit tomorrow? They want to see you."

Olivia nodded. "I want to see them. But I am just so tired and nauseous. They won't be staying long."

Brian nodded in understanding. "Get some rest." He leaned forward and kissed Olivia's forehead. He took the pail out of the bedroom and cleaned it out.

Brian sat at the supper table eating alone. Olivia made it very clear that she was not hungry and would not be eating that night. Brian had made her drink some water, but he wouldn't force her to eat. He knew she was tired and just wanted to get some sleep.

Tears filled Brian's eyes. It was only the first day of Olivia's fight and it was already draining them both. He held back a sob, thinking that this horrible disease could take his wife from him. Brian pushed his plate away from him and rested his head on the table, sobbing. He needed to be strong for Olivia, but he needed someone to be strong for him. He didn't want to think about life without Olivia, but when he hears the word cancer, he thinks of death. He knew many people survive cancer, but he also knew many died. He prayed that Olivia would be one that survives.
