A long story short, my very toxic younger sister has slept with all of my guy friends. She has slept with guys I have been romantically interested in, she has caused all sorts of drama and problems in my social and music world. She has completely and throughly invaded every aspect of my social world, and every boyfriend she has had, has been someone she has met through me.

I even had to send her an email telling her to stay away from my ex boyfriend, and then I found out he stayed on her couch. I am done with her. This is just a short recap of everything but trust me when I say, she has given me no choice but to remove my self completely from her and build up a new social world that she has no part of.

I am too angry and disgusted to even be in the same room as her. It is too triggering for me. My mental health can't handle it. She is on better medication now, but the years of walking on eggshells around her erratic behaviour has ruined me and she is too triggering to be around.

My problem is that my cousin had a baby. Her and my cousin are closer that my cousin and myself. I have been living overseas for a longtime.

I am going to miss out on things like, his birthday parties, etc. if I want to avoid her. How do I navigate things like Christmas? Am I just going to have to miss out on things like this for the sake of my mental health?

I can still see my cousin and other family at other times, but I have to organise away from bigger events, and miss out on the actual good ones. This makes me even more angry.

This person has absolutely trashed my life. If I had known she would have stalked my life when she came and saw my band and immediately fucked my bass player, I wouldn't have even told my family that I had a band at all.

Does anyone have advice on how to handle family events? and how do you stop the anger from surging in and out of your life like the tide?
