I think you are better off without them. Honestly, I do.
I've cut my WHOLE family out, extending out to cousins, aunts and uncles. I felt like I had no one, and sometimes I still do, but what I remind myself is that I am worth a lot more than the rubbish they put me through. I'm worth more than they deserve, and my life is not enriched with them in it, I am better off without them.
It takes time. It's been nearly 1 whole year and I am starting to realize there are more people around me than I thought, and I do not need my toxic family. I even thought I needed their love and approval, but I don't, and the day I let to of that desire for their love and approval a HUGE weight lifted from me. I became okay with the idea that they won't be in my life any more. I could let go and move on.
