So, my sister is really toxic, and we always do 2-person roleplays with at least five characters. They're usually really fun, and isn't very toxic. Until she is(If you saw my previous post, you probably know what I'm talking about). Sometimes, she just leaves and never tells me why. Sometimes she inexplicably refuses to roleplay as a plot-important character, which means the roleplay can't progress, etc. It really sucks. I've been thinking of ending my friendship with her and moving on, but I can't. First of all, we have a tiny house. Second of all, I don't know how to make friends, and I'm honestly kind of scared to. I always think that it's not gonna work out or it's gonna be just like the one with my sister. My life sucks. What should I do?
