Trying to hold on

So I'm 20 yrs old and i still live with my mom cause every time I even talk about moving she starts to emotionally black mail me. Telling me that She took care of me for years and now that things get ruff you just up and leave. Which is not really true, I'm looking to move to get away from the abuse, to an environment where I can have a bad day without her telling me that I cant handle anything and I shouldn't have a bad day and every time I do she yells at me. Oh and drama between her and my sister is getting bad again and i tired of crying myself to sleep.

I know moving isn't going to be easy and it wont make everything sunshine and rainbows but I have my boyfriend Karl and Becca who will be moving in with me. And I found a house that is a rent to own. Its in a good neighborhood and looks really nice and I'm excited to show Karl and see what he thinks. I keep trying to look on the bright side of things cause its hard to see the light in the dark. And I'm starting to fall. But I dont want to so I'm trying get away from the abuse.
