New obsession?

I'm fairly certain that i have pure o because i had a disturbing run in with what appeared to be hocd a few months ago. I was constantly in a state of anxiety wondering whether i was turning gay, however I have dealt with that and although some gay thoughts and worries still pop into my head from time to time it is something that no longer bothers me. The problem is that roughly a month ago i was feeling pretty down and unsocial one day and the thought popped into my head "what if i can't socialize any more?" and since then It's been a recurring thought along with worrying about whether or not I've lost my sense of humor and that I'm not really myself anymore. I've always been fairly shy and as a result my confidence and conversational skills haven't been the best, but throughout the past few years I've seen huge improvements in those areas. This is been making me worried and since it started and i think it's triggered a mild case of depression which is common with ocd right? The thing is sometimes i really doubt it is ocd and I've actually lost who I am and what people liked about me. This is because the anxiety i feel about these thoughts isn't close to as intense as when i was suffering from hocd. Although other times i think it is an obsession because my thoughts follow a really illogical pattern. Like I would feel really into socializing and i would joke around with friends and girls which would temporarily relieve my worries until shortly after doubt begins to set in again and i feel really disconnected and in my head. Sorry for the huge paragraph but i guess I'm just wondering whether you think this is a new obsession or not and whether the depression will go away when the thought pattern stops or if it is a separate thing.
