You know what you're in for...
"I'm living in a fantasy, Amy. I noticed that, but I can't seem to pull myself out." Amy smiled faintly at that, putting her hand on Sheldon's shoulder. Sheldon wants to put his arm around his wife, but he doesn't want to break this illusion just yet.
He only closed his eyes as he imagined the soft touch of Amy, his beautiful, gentle, and kind Amy. It worked for a while before a ghost of cold air reminded him of who's not there anymore.
"I wish I had the strength to do it and move on, but I just can't. I can't make you just a part of me. You are my whole life."
This time, Amy doesn't offer anything as a reply and Sheldon started to fear that even his brilliant mind could not conjure the perfect replica of the woman he loved anymore. It has been a while, and it shouldn't even be a problem considering his eidetic memory, but lately, everything seems to blur.
Amy had stopped answering him. He could not hear her sound any longer. Her touch seems to fade away, getting colder at every moment. What could he do if one day he couldn't even imagine her face anymore? He's barely coping as it is and he just feels so, so tired.
When Sheldon opened his eyes, there's no Amy smiling back at him, just an empty cold room in a barely liveable apartment. What day is it? He remembered Leonard trying to get him out of bed. Or was it yesterday? Nothing makes sense anymore.
"I don't think I can do this anymore, Amy. I'm tired."
A tried sob wrenched to his body before it settled to a more quiet whimper, "Please, take me with you. I'm so tired, Amy."
