Hey there....honestly, if you are going back that far and having a lot of problems, then you need to seek professional help. If you already have, then make another appointment. You have several "what-if" statements in your post and those are the worst for people with OCD. If we could only stop "what-iffing." What you have to do is remember that we cannot change the past nor predict the future, thankfully nothing happened to you and noone else, and move on. We are going to have "what-ifs" our entire lives.
If I didn't have the right tools in place at the moment, the phone call from the Dean of Students at my son's college telling me he was acting irrationally and was taken to the hospital by ambulance would have really thrown me for a loop. He did something wrong, he paid the price, and I have to let it go...just like you have to let it go. These choices we make, they could go either way but luckily yours went the right way. These are all learning lessons in our lives.
Take care.
Wow this ocd is really bad i didnt know it could also pop up in all aspects of life. How is your hiv ocd working out? Remember your alive and well now. What happend in the past belongs there now so no reason to be anxious about it. If you keep lookibg back youre facing your back to the future.
