Hi there, I really shouldn't diagnose, but I'd say you probably have OCD. You sound A LOT like me. I have what people call "Pure O"...OCD that mostly only contains obsessions, hardly any compulsions. When one obsession goes away, it's replaced by another.

I greatly recommend that you obtain professional help...my therapist has helped me so much in learning how to cope with my obsessive thoughts. He taught me not to avoid, because avoiding your thoughts is one of the WORST things someone can do.

It's great that you're on the right track...at first I just assumed that I was a bad person, and all these thoughts would come true. However, everybody has these types of thoughts, but people with OCD just take them more seriously and ruminate over them. This turns into guilt, avoidance, and shame.

If you ever want to chat, feel free to send me a message. Please update on how you're doing, best of luck to you.
