Me and my Bff were best friends for 3 years now. I love her and she loves me and we are both loyal to eachother and trust eachother a lot. The issue is my bestfriend has depression so she's sad all the time. I've been able to help her for 1 year but then suddenly everything changed. She kept getting sadder and everytime I tried to help her it wouldn't work. A year passed by and things gotten even worse. Now we argue a lot and get sad like literally everyday. Sometimes I just feel like leaving her but everytime we argue it's like she knows I'm about to leave her and she tells me to do it and then it makes me not want to do it because it makes me feel bad. I understand she has a depression so I try my very best to support her and give her advice when she most need it. I also give her gifts and compliment her so she won't feel so sad all the time, but the problem is she's rude. Everything I do gets her angry. I can annoy her and she pushes me away. She hurts my feelings but then says it's a joke and gets mad at me for getting hurt. Then she says sorry for hurting me or whatever and then the next day she says I wish you would say sorry for once when you do something wrong. Thing is I do say sorry when it's my fault, but she doesnt realize it. The point is it's gotten so bad till I just feel like I wanna die. I can't even say how I feel without her judging me or thinking everything I say is about her. I just need some advice on how to make this friendship better because she really is special to me and I really love her and I dont want her to be sad anymore. I just want her happy. She has been in two different types of therapy and not one of them has helped her in anyway. Also, one of them actually created some conflict in her life. She's been prescribed medicine once but her mom refuses to let her take them. Basically, I'm her only option.
