kronas I've been thinking about this today.I think you need to find some regular activity like the charity shop thing and to try and keep to a regular sort of timetable every day.Get up at the same time and eat at regular set intervals.Try to go to bed at the same time every night.The more you work at that the better.
How about just taking as interesting photos as you can of the people in your area.Take a look at the winners of the first section of
Online Photographer of the Year for 2004.It's not about the area but the people every time.I'm sure you can get some interesting pictures AND get out to meet new people this way perhaps even some girls.
Or try to work on your poetry at a regular time every day.Write something every day and see what you achieve? Write a story perhaps?Please don't say you can't,that's just the depression talking.You already proved that you can achieve anything if you are determined enough.You just have to find something that you can fit around your problems without letting the problems overwhelm your dreams.
Not knowing you well enough I can't know all your abilities.Perhaps compiling a (positive) list of your strengths,abilities and interests might give you some clue as to what you can do.Leave out the negative stuff completely and concentrate on can do's.
Incog.
