Hi BrownCurtains,
Just a few thoughts..........
Losing interest in the things you loved to do, feeling empty, feeling numb, feeling restless (e.g. in boredom) can be signs of depression.........so maybe something to think about/talk about/look for help with???
But the things you've lost interest in...........maybe look for different things which might attract your interest a bit more???
The watching TV all day...........maybe schedule specific things in amongst that and try to give yourself that push to do them/some of them???
The time alone.............if that's too much for you, do you think maybe you could hook up with friends/family a bit more, or even look at different/new social activities you could do??? Or even break up some of that alone time with phone calls to friends/family???
Just some thoughts...........and here if you want to talk more.

You might also want to check out the forums for Depression and Self Injury too. There are plenty of really understanding and supportive people around them as well as around this forum, so whatever/anything that helps a little.

AND, welcome to PC!!!!!
