help!

okay, so people say you get moody on your period, generally I'm just extremely moody. recently I've been having trouble with my boy friend, I met him in September when I tried to kill myself, I fell for him in all honestly, but recently I've been getting bored. he's such a good guy and I couldn't ask for better. I'm also dealing with depression so I haven't been happy and i'm not sure what it is. other than everything going on, I feel awful because I tell him I don't know what o want. he's so great and I just wanna be in love with him again, I've convinced myself thank don't deserve happiness. so I stopped being happy on all aspects, what do I do, i don't wanna break his heart? :(
