To phoenix7,
although I don't have the full story about your situation, I think that it's normal to have this checking behaviour because it kind of reassures you that everything is ok. Maybe one thing you can try is to make a list, as in ticking the number of times you have done checking? (This would also serve as some kind of reminder as to how many times you have done checking) Hopefully, this would help.
Anyway, you are not alone in this. Take care
