I was having a good day and my OCD makes me "feel" that I have been wanting to leave my gf for months. Telling me that I have felt this way for ages and that I AM going to do it.
I then panic and think "oh no that's horrible I don't want to have these feelings. What if I break up with my girlfriend? I don't want to break her heart and it will break mine. I have a lot of issues due to all my OCD amongst other things but I love her and want to make things work"
Then I realised... IT WAS OCD AS I HAD A "WHAT IF"
It pisses me off that it can make you feel things you don't actually feel, just to start the cycle. It's like it sometimes partially or fully makes up a trigger and tells you it's real so it can give you "what ifs"
