The only and best advice I can give is to dump her as a friend and move on. She’s toxic to u. You have to care enough and more about your own needs than to worry about hers. She’s dragging you down and draining you. What are u getting out of it? Seems she is no longer the friend she used to be. Get out and find better people who lift you up and who are supportive of you. I would just honestly stop calling her and avoid her calls entirely. Sounds mean but she’s toxic and is doing you NO favors. She’s not a good friend.
