Sick & Tired

I'm sick of being awake all night. I'm also sick of being sad all the time. No amount of therapy helps, sorry. I can talk about things until I'm blue in the face, and it doesn't make any difference. My plan is good, and I'm going to do it, but it seems so far away. Will it work? Will it make me happy? What do I do in the meantime? How do I make it through each day?
