A/N TVTropes calls Jessica-type characters the Eeyore, the Prone To Tears version.
Jessica woke up feeling very blue inside. No happiness for me, she thought. No hope or enjoyment. I'm so worthless, I've got no reason to live. I can't enjoy anything, concentrate or make decisions easily.
Jessica's crew arrived and she began to cry, wailing sobs and she sniffled, long and loud. Her face was covered in huge, thick tears.
Jessica's driver climbed on her buffer beam, then pulled a cotton waffle cloth from his pocket to softly dry her tears. "There, there, Jessica. Let it all out. I wish I could wipe your unhappiness, so I shall wipe your eyes.". He gently rubbed her sodden cheeks and wiped the tears from her moist eyes, looking at her with empathy and compassion, listening attentively to pick up on her values and cues and trying to understand how she felt.
A rude engine said, "There's the cry-engine, bawling her eyes out again."
Thomas pressed his buffers hard against hers. He smiled at her, his cheeky, sweet smile in a cheering up a friend way, saying, "I can see and hear your crying. Emotion's part of life, so just cry. You've got the right to cry, though I wish I could help you feel better. I don't like to see my friends having a hard time with emotions."
Jessica let out another wailing sob, fresh tears welling up as she cried some more. I wish I could enjoy having my tears wiped, she thought. She sniffled again, hard, coughed as she choked on her sobs and hiccupped. She gasped and gulped, shaking as the tears poured from her eyes, not once stopping and let her driver comfort her.
He said, as he continued to wipe her tears away, "Just go ahead and cry into your cotton waffle hanky. I'm here for you, just to dry your eyes. I love to wipe your eyes." He tried to reassure without being overbearing, patiently listening and supporting her in her pain, doing his best to provide empathy without being pushy and over-intrusive, just provide his attentive and practical comfort as he held the cloth to her eyes and wiped all her tears away as best he could.
Jessica wept and wailed non-stop, hard and loud as ever she could until she had no more tears left. Her driver dried her last tears away, patting any stray huge water droplets from her cheeks and dapping tears in her eyes away until they were dry. He went back to the cab with the sodden cloth. Her face was all red and her sore eyes were flame-red and puffy. Thomas shunted her to the water column and her crew gave her a drink.
Jessica pulled her first train, her large, dark eyes, black as her coal, downcast and soulful. She stopped at the last station and burst into wailing sobs. She was very sniffly, like before.
Jessica's driver was on her buffer beam to comfort her. "Remember what I said earlier. You've got the right to cry," he said, drying her tears with a cloth. He rubbed her sodden cheeks and wiped her tear-filled eyes.
Jessica cried some more, tears welling up in her eyes. She was sniffling hard, coughing, choking on her tears and hiccupping. She gasped and gulped, shaking with sobs as she wept non-stop and let her driver offer comfort.
He said, as he continued to wipe her tears away, "I shall wipe your eyes dry of tears, as I did before. I know there's no relief in your tears, but you're calmer and can think better because of your sobs."
Jessica's weeping and wailing went on until she could cry no more. Her driver dried her last tears away, wiping her cheeks and eyes dry of tears, then went back to the cab with the sodden cloth. Her face was bright red and her eyes were flame-red and puffy. Her crew gave her a drink.
Later on, Jessica had her therapy with Dr. Tom. She sighed and whistled sadly.
Dr. Tom said, "Tell me how you feel today."
"Horribly sad and worthless. I'm a Really Useless Engine and there's no hope for me," she said. She began to cry in wailing sobs, huge tears wetting her cheeks.
Dr. Tom said, "Brilliant. Those heartfelt sobs are splendid. I love it when the sadness falling down your face is from the heart."
Jessica's driver climbed onto her running board and when he got to her streaming face, pulled out a cotton waffle hanky to dry her tears. "Cry it out, Jessica. This is a safe place to shed tears," he said as he rubbed her sodden cheeks and wiped her streaming eyes.
Jessica finished her cry and the session went on.
"Well done, Jessica," Dr. Tom said.
Jessica's fireman said, "Tears are beautiful. A waterfall of sadness can provide relief."
Jessica said, "I've got Driver to wipe my pain away with my soft cotton waffle hanky whenever I cry with him there."
Dr. Tom asked, "Jessica, how does it feel to have your driver let you sob into that hanky?"
Jessica said, "So soft. But I'm still too depressed to feel anything other than sad, hopeless, worthless and useless. Why don't they just scrap me? I've got no reason to live."
Dr. Tom said, "That's just your abusive driver. You were loved by whatever fireman you had then and all your drivers and firemen after, the heritage railway controller and now the Hatts, not to mention any friends you've made, like Thomas. Your Sodor crew, the Hatts and your engine friends would be dreadfully sad if you were scrapped."
The session came to an end eventually. and they went with their respective days, Dr. Tom, along with Jessica and her crew, who gave her a drink.
Jessica finished her work and wailed herself to sleep in her shed with her driver drying her tears and Thomas giving her a buffer press. Her driver blotted her face and eyes dry of her last tears, then left with the sodden cloth as Jessica fell asleep.
A/N Not sure when Jessica should reasonably have a breakthrough, as she has daily therapy, like the book woman depressed in a mental hospital I've read about.
