Aitah for sending out a public apology regarding my brother, on tiktok

So a couple minutes ago I got of tiktok live with tears in my eyes and my body in shock. for context I am an artist and make coloring books and have long awaited the days I would be able to go live on tiktok and color in my books live. it’s a lot easier and shows real time support. rather than spending hours on a page for a seven second tiktok that gets five views. it also gets pushed out to alot more people imo. I have been going live for a couple hours at a time everyday for around three or four weeks. my account is super new and under 1k followers. going live is a little bit mentally consuming for me as i’m a naturally anxious person and it’s an environment with a lot of people. I logged on earlier than usual. I typically start my streams around 11/12pm and end around 1/2am. I logged on at 9pm as i’m trying to fix my sleep schedule with commitments and classes coming up for me.

My brother (16M) was at his sport and my mom was working. My dad was in the garage and the house was quiet enough. I started to color a more detailed page and I was feeling good. around halfway through (11pm) my brother walks in, we’ll call him Jack. Jack has never seen me go live and is usually asleep by the time I start. he didn’t know I had started doing it. I pointed to my phone and sort of let him know I was on. he looked confused. someone sent me a gift and I thanked them. Jack understood. he looked at me with amusement and said “ you’re live?” I said yes. I should have paused it there.

For whatever reason he thought I wanted him breathing down my neck and commenting on every little thing. He started looking over my phone and sayinf things. At this particular moment I had only 2 people in my live. He started to make mocking comments about how no one was in my room. Jack only got worse from there. He kept mocking my stats. one of my viewers had single-handedly given me 40k likes. Jack said he didn’t believe it acting like it must’ve been a glitch or something. He insulted my supporters and told them they shouldn’t spend any money or time supporting me. Jack made fun of the people watching, calling them by name. I felt hurt and I was upset that my brand took the front line for his public insults. He got worse. Insulting my work, saying “we all have highs and lows but you must be really low”, commenting that my ability to get a job must be hopeless if i’ve “stooped to this low” (I have a medical condition that has made school and any possible employment really hard, which is how I ended up selling my art in the first place.) He asked “what if I just flipped your phone and gave them a face reveal?” my account is faceless. He made rude comments, attempts to mess with my phone and press buttons, and also refused to leave. I was in a state of shock and upset, and didn’t speak a word the rest of the live, after finally getting him to leave only after having to forcefully push him out.

After the live, I put an apology on my story. Idk if it was immature or hasty but I did it. it reads:

to everyone that was in my live earlier I apologize if you had to witness one of my family members acting out. I am so sorry if you were insulted or uncomfortable. I will do my best to make sure he doesn't relentlessly come at myself and my viewers also. this is my formal apology for any rude remarks he made towards you.

My account is public so I dont have limits on who sees it. I worry that I was petty, and it wasn’t needed. aitah? should I take it down?
