I have experienced obsession and compulsion in lots of places over the past several years, but the only one that really seems to stick to me is a feeling that I have been insulted. More especially, that my private relationships have been disrespected.
What makes it hard to discount, according to my understanding of this silly thing I (and many) seem to do over inconsequential things, is that these insults do bother me - I find them genuinely disrespectful. It's not like the obviously arbitrary need to check a lock I know I checked, etc. I will not try to summarize the over-arching, long term process of working with these kinds of obsessions; suffice to say, I eventually almost always get to the point where I am compelled to contact the person who issued, what I feel is rationally a rude thing to have said (words carry weight), but the feeling in result isn't relief. It may be, a little, but then I'll delve into further details, or I'll hop to something else I've churned up (these tend to piggy back, I've found) and then I'll be desperate to get over something all over again.



(yep, those three faces tell a whole story)
It's hard. I know I'm doing something very irrational, but I also become annoyed with the fact that the person also said something that was very rude - they acted strangely, too, in a way, and it's hard to look at getting a hold of the obsession as having command over myself, when I also feel like I'm giving command to that individual.
Anyway, I really welcome feedback, insight, shared situations, and so on. I think talking about this kind of stuff with people who understand, goes way further than coming to the conclusions yourself.
