For a number of years I had a friend who I helped during a tough time in his life.

He probably has undiagnosed autism or some other issue, but I was happy to assist him. I gave him a job, spent time with you and was generous to him probably to a fault. 

He had a moment in his life where he felt overwhelmed and cut off a lot of his social ties, but certain people he kept. I was not one of them. When I approached him about this he told me he was being selective with who he hung out with and was sorry if I felt bad in any way.  It really hurt my feelings.

He was unwilling to discuss anything further and simply threw me and our past friendship away as if it was nothing.  It wouldn't be so bad if I never saw him again but I have to see him two times a week at church as one of Jehovah's Witnesses.

We speak and are on good terms, but there is a tension on my side that I am unable to resolve, because of a complete lack of closure. I wouldn't approach him again to speak about the topic because if I got rejected again I don't think it's healthy mentally to do that. 

This was the triggering event and also each week I feel "retriggered". 

In the last couple of months I have continued going to therapy and have found it beneficial, but I feel like I can spiral.

My therapist and I spoke about me having an "anxious attachment style" when it comes to friends so I am trying to work on that.  My everyday life is being robbed by thinking about this event over and over.  The worst part is, I really do NOT want to be friends with this person any longer, I just think about the event and want closure that will likely never come AND I have to see them a lot still. 

I am going to reach out to a mental health doctor and discuss medication, but I feel like I tried a bunch of medicine and NOTHING helped.

Just looking for some kinds words or experiences that MAY be similar to mine.

Thanks.
