My mom tells me she wants us to be close then does shit like this

My mom always says she wishes we were closer and asks why I dont tell her things. My mom is a person who was always on my side no matter what and looking back that actually was terrible for me. I'm almost 30 now and after some years in therapy I finally am learning how to behave in society and take accountability. I feel bad for my teachers because my mom defended every single thing I did in school. I was awful to people. When I got in trouble for bullying my mom was in that meeting with that teacher and defending me when I shouldn't have been defended. That turned me into an awful person. I'm so embarrassed to admit this but when my high school boyfriend broke up with me on my 16th birthday my mom went out of her way to ruin his life and at the time I thought he deserved it but thinking back she was harassing a 16 year old.

Whenever I tell my mom thinks she goes hard to defend me even when she shouldn't. But even in moments where I feel I'm in the right she takes things too far. She did that recently. I had an issue with my hair dresser. I felt like I did not get what I asked for. I hated the way my hair turned out. It was patchy. Me and her kind of got into it because she wouldn't give me a refund. I made the mistake of telling my mom and my mom wanted me to expose her online. I wasn't gonna do that. It's not like she fried my hair off. I was just gonna dispute the charges with my bank, not see her again and call it a day. Well my mom took matters into her own hands and asked her friends and told them to tell their friends to start review bombing this girl and my mom posted on our cities facebook calling her out and being horrendous.

The stylist boyfriend had reached out to my mom to tell her to stop sending people to harass her. That he has kids and stuff. My mom decided to make this Facebook post about him "outing" him as a predator. She said how he lost custody of his daughters to their mom who is on drugs because he molested on of their friends. I asked my mom how she knew that because you can't just say things. She said she heard that A STYLIST had a boyfriend who was caught molesting his daughters friend. That this stylist works on the same part of town as my old stylist. That does not mean that was him. You can't just call someone a pedophile with 0 evidence. Now everything is so far out of hand that he's saying he's gonna sue my mom for defamation of character because her lies could have gotten his daughters taken away. I tried to handle this like an adult and my mother has me looking like an idiot. This is why I do not tell her things. Because she does insane stuff like this and I feel dumb.
