OCD tendencies

I remember when I first started feeling like this- the only way I could put it in words was that I was just obsessed about being gay and I thought about it twenty-four hours a day. I typed it into google and this whole new world opened up to me. I suddenly was faced with a whole prospect of possibilities of HOCD and the idea was wonderful to me. I was constantly seeking reassurance, I was constantly testing myself and checking for reactions and I could see where it had all started! I knew it my hart this was OCD. I has had OCD before but hadn't realised. I had become obsessed I was doomed and I was constantly waiting for bad things to happen. I had a massive phobia of vomiting and I wouldn't do things like sleep in certain pyjamas or lie the same way in case it made me sick.The only way I would let go of these obsessions was to do them but it wouldn't work.
