I would suggest that if you are feeling like sleeping all day that you should go out and volunteer or even better find a job. Try and integrate back into society and face your fears. Try to get through that last anxiety attack faster than the last time you had one. Try to face a crowd and not get nervous.
Getting over the fact that your boyfriend broke up with you might not be simple, but it is far from impossible. You are going to have to commit to picking yourself up, dusting yourself off, and moving along.
Don’t swim in negative or depressed thoughts. For some reason, when feeling depressed, some people want to wallow in it and deepen their depression by engaging in behavior such as listening to melancholy music, staying in bed all day, drinking all night, or having meaningless sex. Recognize these behaviors for what they are. These behaviors are forms of self-punishment or taking your anger out on yourself. You deserve much better, so try to pull yourself out of depression by treating yourself with love, instead of anger.
First, I learned that depression and crazy is hereditary: a person may inherit the whole thing or inherit it in part, the fullest cycling or a lesser cycling, or one may get either the manic side or the depressed side. It was truly a revelation. It explained a lot about me, and my brothers and sisters. Knowing this, we have a much better chance of trying to control it.
