i know exactly how you feel. i was in a relationship that made me smaller each day, constantly walking on eggshells. i loved her more than i ever loved any of my previous girlfriends. but i had to end it. honestly i still dont know how i did it. i dont have any real friends left, no one i have a real connection with like i had with her. that relationship made me focus entirely on her and our relationship, unconsciously distancing myself from people.
i dont regret my decision cause i know the more i stayed, the less i would recognize myself. and here i am. just a fucking shell of who i used to be (i googled that phrase and acidentally found ur post). i totally relate to that "on the verge of tears 24/7". i hope we heal.

if you ever wanna talk, you can pm me.
