Sounds a bit like my family when I grew up. Then my older sister died, and everything broke down. I've experienced so many personal tradegies in my life, I almost feel like an expert. I had a breakdown in my mid thirties, but I survived, and after a while, I felt stronger than ever before. When I was 40y, I was in a serious accident and I got bad injuries. The following 2y, I didn't wanna live, at all. I was really close ending my life, but I failed because the mixture of meds wasn't enough, probably because I had built up high tolerance. The second time, I couldn't complete because I thought about my son.
Today, I don't wanna die anymore, and I actually feel ok, even though my latest flame dumped me yesterday. I've been working really hard to tell myself that; I'm worthy, I'm a superwoman, I'm a good friend. I decide who I am. My shitty childhood doesn't define me.
All the best for you.
