I have hobbies, but nothing is fun. It's like being in a hospital, you do things to pass the time.

All you gotta do is keep doing the next right thing. Maybe look into upping your meds? I know it’s hard. I suffer from bouts of depression that feel the same way. I refuse to give up because I know there are so many people who love me including myself (took ages to figure that one out). There are folks who love you and want you to succeed. Start doing some work towards making yourself one of those people as well.
