This is gonna be a long story so buckle up. I a 18 year old female was adopted at 15 with my 2 younger sisters, now 10 and 9, by my best friends family. Life was ok for a while, the girls took time to adjust but it was ok, but it just got worse, the youngest threw tantrums daily and hurt others and herself often, often lieing and stealing as well. Eventually it got to the point we were scared of her hurting the 10 year old and stuff and put a camera in their room, they never changed in it or anything but it was to make sure everything was ok. One day the 9 year old decided that because my now Mom didn't want to get her a rainbow dash toy that she would tell her teacher that our mom or her which eventually resulted in my mom being arrested. That charge was eventually dropped and we slowly got our life back together until the second time, the 9-year-old threw a massive fit and my mom had had surgery at the time, I don't remember what it's called but they took out her ovaries, and was in a lot of pain and really weak but the child had a extreme meltdown and pulled out a electrical wire from the outlet halfway and tried to touch it my mom grabbed the first thing she could on her which was her hair and yanked back so that she wouldn't accidentally kill herself. This also got my mom arrested for the second time we got her out on bail thankfully but she was not allowed around the littlest for obvious reasons the girls were taken back into foster care and that was that eventually we found out that because of the court order that my mom couldn't see the youngest she was never home when the youngest was, this is after the girls got back home, but she was here during the day not knowing that apparently she wasn't allowed to be at home at all. She was arrested for breaking the order when as soon as we found out about that specific part of it she never came back to the house again. We were trying the best we could to stay positive the girls were still in the home, until the 10-year-old decided that she wanted to go back to foster care so badly that she would tell the cops that my father is ate her which is completely untrue he is the most bland nerdy least sexual dad ever. They took the girls into foster care again but found nothing on my dad they are still currently in foster care and honestly I hope they stay there. This all happened within the span of like a year and a half, and honestly I don't know if I can never forgive them. Even if I am their biological sister. Today was my mom's bail hearing there is none so she is stuck there. I know family is stressed over money and utterly exhausted emotionally and my dad physically. This is just a broad explanation of this entire situation I'd be happy to say more later but honestly today I'm already just so done. But am are the asshole for not wanting to see or talk to them ever again?
