Relapsing from depression and becoming a slut?

I have been suffering from bad depression/anxiety for about two years, and it went away for a few months and i was really confident and comfortable with myself, and just really happy. I think what made it go away was the fact that I became in control of myself and i wasn't afraid of the things i used to be (social interactions and such). For some reason, it just came back last week and it is worse than ever. Now that i know what it feels like to be confident in myself and that i have gone back, it is making me worse than ever. When i get this way i just get really closed up and cannot really interact with people normally and i become awkward with people. I've decided that when i get depressed and relapse, i will become a slut (not sex necessarily) to have something to do with my life. This makes me really sad because i know that i deserve better but when i feel this way i cannot even keep up conversation. Help!
