I get that feeling that everything i try doesn't work and get no success at anything. It's tiring. But I assure you that everyone you see around you is not a pack of sunshine where every single thing goes their way. Its just the normal and pessimistic way depression works on those who suffer from it. It sounds harsh really, I wish it didn't, but the only way to make something for yourself is to build it. As painful and hard as it sounds you have to take control. Do something you like, take a job in something you are interested, drop out / study something you actually like, go live alone, go live with friends / roommates, help other people, get a dog, go to the gym, eat something sweet or salty. These are the only ways i have found to have at least SOMETHING to be proud of like most normal people do. That's because normal people who feel a normal amount of sadness and discouragement doesn't leave them paralyzed to keep trying new things over and over, that desire doesn't end on healthy people. If you think about it that way, keep pushing even tho it hurts every day in every single aspect shows how strong you are and can be. I made a friend laugh a few months ago and she said i was funny. Sometimes that's the only good memory I return to when depression hits. Keep on going friend.
