Ramble on my abandonment issues lol

Today my friend told me I was going to leave her ones we graduate and that im replacable. She's probably projecting on me, but i cant help but think its true when ive always put on this armor, to abandon them first or emotionally detach myself for when they abandon me. Ive had 2 friendgroups in Senior and both of them thinks the same: that im going to leave first. That im distant. Maybe i should. Maybe- no, i am. Prove them right, shut them up, that i am who they think i am. I was never cut out for this friendship thing, i wish i never met any of them. I wish they could just leave me alone.
