I 18F am not good at anything

There is not one thing in the world that I'm good at. The things I work for very hard are easy for everyone else. I don't have energy for anything, when I try and put energy in something I try hard just to be mediocre. I procrastunate alot. I'm embarassed. I can't face people. The closest people have just made fun of me today thinkings it wasn't a big deal instead of supporting me. I feel betrayed. What can I do to get better?
