Sounds like conditioned response to me.
I don't know how your childhood was or anything, but it sounds like ... if I had to guess ... that maybe you were used to 'major consequences' for things done wrong or that no matter what you did or didn't do, you've had some people leave you at some time.
If you expect to be left for normal interactions, and you "hide" yourself from these friends afterwards ... somewhere inside, you may be reasoning, that you better leave first, because they're going to leave you anyway ... so why wait to suffer that hurt ... leave first instead.
Some how, they don't see the conflicts you're talking about as that big of a deal, but for some reason you are ... so you must somehow be used to suffering consequences that outweigh the action or that were overboard or maybe not even merited in the first place.
I don't know personally, why you leave - they don't - why they don't see these conflicts as badly as you do ... but I can only guess, with what I've said above.
Too bad you don't feel the same way about yourself as your good friends do.
Maybe if you ask them ... they can help you to see what they see in you. Or ask them point-blank, why they stick around.
The fear of being "left", is a Biggie. Always easier to leave first or just not have as many people IN our lives, who could potentially leave us anyway.

Seems to me you have trouble forgiving others in the same way you have trouble forgiving yourself.

Low self esteem goes hand in hand with depression. Most people dislike confrontaions but for me, everything seems to be magnified. I go out of my way to make sure that people aren't angry with me at the expense of my own views sometimes.
Learning to love ourselves and see ourselves as those who love us do can be hard . . .I know, I'm still working on it!
Try to keep those friends close. Let them know how you feel.
Take care,
