I'm feeling so overwhelmed, I feel like I am purposely pushing my closest friend away. She has come back from a 9 month trip and in the time she's been away I have become self reliant emotionally as I cannot deal with putting this on people and I've forgotten how to be close to someone I don't want to be vulnerable anymore I want to keep everyone at a distance so I don't have anything to owe them and I know my anxiety can throw me around and make me regret most things and I don't want to share this anymore I feel more comfortable being miserable by myself. I am so scared at this feeling that I can't open up and I don't actually want to but upsettting her and thinking of the things she's seen me goes through makes me feel so vulnerable and petrified she needs to find some other best friend I can't take the responsibility what do I do?!?!
