TIFU by ranting about my sister… someone heard me and now I’m scared I’m going to end up in jail.

I’ve (F26) been posting here a lot about my ex boyfriend (M27) of over 5 years who I caught getting sex workers behind my back. Important context for this situation is that we live together in a rented home with his whole family including his mom (F52) his brother (M28) and a couple others.I don’t have a family of my own, but I used to.

Growing up it was just my mom, me, and my little sister. My mom was extremely neglectful and harmed the both of us a lot. I effectively raised my sister until she was 15 and I was 22 when ultimately I accepted that I was in over my head and had to call CPS on my mother. My childhood was so bad that I’ve been diagnosed with about 7 disorders including CPTSD. I am managing well with medication and therapy and I know how to ask for the help I need when I need it.
My mom had physical custody and I technically lived with them but I was gone working and with my now ex boyfriend so much that I could avoid home for weeks at a time.

In that time my mom and sister didn’t clean at all so the house got hoarder-level disgusting. My mom stopped enforcing going to school and started letting my sister sleep around at random boys’s houses. I couldn’t handle it anymore so I reported everything.
Initially I’d set up a program with CPS that would allow my sister and I to find housing for a while and help finding stable work for my sister once she turned 16 as well as a good high school program that would help my sister go back to school. I’d explained that to my sister for hours with my boyfriend and my brother both in the loop and there when I told her about it.
When the day of came my sister refused to go and elected to go stay with a family friend in the next city over. I spent weeks cleaning up the house because my mom ran hundreds of miles away and the eviction process would cost me thousands being the only person on the lease in town.

CPS in our city dropped the case because the endangered child was now in another city. CPS in my sisters new town refused to give me any information because I wasn’t her parent and had no legal right to any.

I got a second Job to pay for lawyers to try to get custody. I worked with all kinds of programs looking for help but I was hit with issue after issue. I was working 18 hour days and my sister was getting increasingly frustrated and upset with me for not visiting enough and not being there for her enough.
I tried so hard but nothing worked and eventually I resigned to the fact that I had no legal options without having to spend thousands of dollars I didn’t have. No matter how hard I tried, nobody was going to let a 23 year old adopt a 16 year old.

My sister never forgave me for that, and when my therapist recommended I invite my mother to our sessions to try to work through some of my issues.. that was the final straw. My 18 year old sitter cut me off completely.

Honestly I felt and still feel really defeated about it. Nothing I ever did was ever enough and now I’ve lost the person I was doing most of all of it for.
Even though I wasn’t always visiting I tried to still be there. I showed up for big things and dropped everything on multiple occasions to help her with things. I bought and paid for her phone starting from when she was 11 and continued until about 2 months before she cut me off completely.

On Mother’s Day I received a horrible, nasty message from my little sister. It was exactly a year since we last spoke. It broke something in me. I was collapsed on the ground sobbing. I’m in the middle of leaving my boyfriend after he cheated on me and the person I love the most just sent me a message validating every single one of the worst things I think about myself.
I have this out of state friend that I met when I was around 13. We’ve always been close, genuinely like a sibling relationship since we met so young. I called him while I was on the floor crying.

It was about 2:30pm, midday, so I allowed my voice to raise a bit in my heavy emotions. I said “why is it that everyone that’s supposed to love me doesn’t” and that my heart was broken, that my hope was dead and that I had no idea what I was going to do when I’m alone and so clearly unloveable according to the people closest to me.

The conversation was about 15 minutes long.
That night I found out that my ex’s brother was home and told him and their mom that I was yelling for hours so loud that the walls were shaking. He said that I was talking about how everyone that was “supposed to die wouldn’t die.” And that was going to “destroy everything”. His mom believed this 100% And they both demanded that my ex tell me I have to leave immediately or they’d call the police.

Once they all got home and found that nothing was broken, I was acting completely normally… it just became more evidence for them that I was insane. To them I was acting irate and then normal seconds later when about to be confronted. In reality, I was crying and emotional and it was hours before anyone else got home.

Now everyone in the house is acting weird around me. They all believe that I was saying those horrible things I would NEVER say and because I’ve been open about my CPTSD and mental health struggles. Crazy is crazy to them, and my CPTSD and his brother’s mishearing me is enough for them all to completely write me off.

I have no idea what to do about any of this anymore.

TL;DR: my ex’s brother misheard me on the phone and is convinced I’m a crazy psychopath and has convinced everyone else the same.
