I'm going through a severe depression coupled with OCD - right now the obsessive thoughts center around my relationship - and I just feel completely numb to all good emotions. Worst/most distressing, I can't feel the love I KNOW I have for my girlfriend. Can depression cause this? This change literally happened in a few hours; I went from feeling completely in love with her, as usual, to having a massive panic attack over the idea that I didn't love her (even though I didn't have any reason to think that; she put the idea in my head accidentally), and from then on I've been totally numb. Don't feel anything. Everything I usually enjoy, I feel nothing. Is this depression? I don't want to be falling out of love with her, and I don't think I am, because it seems like it just can't happen in a few hours...but why can't I feel anything? I feel so guilty and anxious and miserable.
