Anyone else super quick to cut people off?

I’ve had people to some fucked up stuff to me and now I’m completely alone because whenever someone does something even slightly wrong (ignoring a text,flaking on hanging out) I cut them off because I don’t trust anyone I have severe trust issues I’ve suffered severe abuse throughout my entire life multiple times with multiple different people and now I’m completely alone because I cut everyone off.does anyone know how I can fix this?i start counseling on Wednesday I’m just so angry at th world..I’m tired of cutting everyone off for every little mistake...I can’t help it.
