When my MIs are bad, I start feeling like I need to fix things including stuff that isn't my fault (at work and home). When you're constantly cleaning up after others--it leaves no time for you to take care of yourself and be successful.

Sometimes people get sort of aggravated regardless of what we do. If you hadn't blocked her from fb, is it likely that she'll find other things that you do are upsetting? If so, you might as well do what you want to do short of outward disrespect and doing something that will get you kicked out before you are ready. I know you are working toward moving out so I don't think you are using your parents since you work and are always trying to improve....
