In trying to catch up on all the posts, one thing really stood out to me: all those multiple schools you have been to. This definitely did not set you up for success when it comes to establishing and building relationships. It would certainly add to those abandonment issues too. You weren't allowed the opportunity to have meaningful relationships and it would have reinforced the inability to meet peers as well. As someone who changed schools multiple times myself, this really speaks to me and I am so sorry to learn you have gone through this.

It sounds as though your mom is what is now being termed as a 'helicopter parent'. No wonder your frustration at trying to establish some independence. I think you said you work. Is this an opportunity to escape mom entirely or is she involved in that too?
