I think that is a normal thing, but doesn't mean everyone gets that, but is not an abnormal thing. I also feel it is something that can come and go over time,as one moves on with their lives and the many phases/changes we all go through. It is good that you have come to recognize this,once I did, it became something my former T and I worked on. See if you can do th same, it may help. During that time too, if I had to move (geographically) I would come right out and tell former friends, that I am weird about "goodbyes" so if I do not say "goodbye" and see them that last day where or whatever homes we had lived in, to not feel I ran away from them or never cared. In fact it was the caring so much and fearing the following depression to come,that I use to get, was one of the very reasons I would wimp out and just get in the car and go off to our nest home.
Weird, to some,but in therapy I found out I wasn't so weird, but needed to try to lose this. I confess I do not deal with this anymore cause I'm sort of a loner. Being a "loner" may also be part pf that too, almost like "if I do not have friends, I won't hurt or be hurt"?
I don't know if this reply is of any help to you, so if I am rambling, just ignore it, I tend to ramble sometimes.

Take care now,
DE
