I'm not depressed I just don't feel like livin'...?

Yep. You heard me right. I have a couple serious medical conditions. One of them being sleep and the other being neurological. They prevent me from doing just about everything I want to do in life. In order to not shake incessantly and communicate I need to several medicines and exercise helps too (when I'm not too tired). The kicker is I have to work all day in order to earn the money to pay for the health insurance and medicine. Work is difficult because of no sleep. Exercise is difficult because of no sleep. I can't go on disability and even if I did I'm in my upper 20s and nothing looks like it's wrong. People at work ume I'm fine and I can't tell them otherwise. What's the point if it all. I've tried therapy but there isn't really anything to fix. I'm a positive person. I like to laugh. I like the small things in life. I just think it takes too much effort to get through this life. So, the question is, what do you do when your not depressed, exhausted all medical options, and can't do this any longer. (Please don't say wait for the miracle)
