Parents going ballistic after I kept my word
So, it's a long story but I'll try to make it as concise as possible.
I (25F) live with my husband (28M) and little sister (18F). She's been living with me since she was 15. Besides the very minimal financial support, our parents are not present in raising, disciplining or caring for her (nor have they been there for me).
For the background, our whole lives, they've been enveloped in their own drama, and I'm not exagerating when I say DRAMA. They fill out divorce papers once or twice a year, constantly call with their own relationship problems, I've hosted my drunk and depressed from relationship problems father couple of times. Everytime it happens, I feel like I'm trying to solve everyone's mental problems.
This time my mother (46F) made a scene at my own home, which is already not OK with me. After that, my father (52M) got drunk and I had to sober him up for two days, not to mention life goes on, so I had to go to work and university. We made up for maybe 2 days, before another bomb was dropped - my mom had a dream, that my sister "killed and discarded her children in the trash". Now that was a big hit, I have to admit I went a bit ballistic. My sister, as I said, is 18yo, doesn't have children, just got accepted into a big university in our area for a very competitive field. This did provoke me to file for child support, and basically to revoke their parental rights (tbh I had the parental rights for half a year until she turned 18).
So now my parents are saying I'm splitting the family apart, I'm acting like a b*tch and turning everyone against them. And to add some spice into the pot, I got a call today that my father "collapsed". I panicked, called everyone around them and apparently it was fake.
Please, good people of reddit, advice me what to do and what to think. Have any of you been involved in any legal battles?
