Why won’t my brain shut up from talking to itself all day and night and I can’t shut it off is this a habbit Iv picked up or anxiety

I'm new and I'm really trying to control thoughts of replaying interactions I've had or things I think might happen with the people around me. This is something constant, and it causes me to repeat actions. Then I lose track of time and often end up being late. It has always affected my sleep and becomes a part of my dreams, which are also always vivid. It's always been hard for me to get up. I just constantly keep replaying different outcomes of things that it haven't happened yet going over every possible outcome with no correct answer. I'm scared of what I might say and do when at work because it's been getting worse lately. I've been terrified of socializing, because I feel like I'm going to lose it every time I speak to someone. I work directly with people doing their hair. I don't want my clients or co-workers to catch me in the act of one of my rituals or it to effect the job that I'm doing. It just makes me angry that I haven't been able to control these thoughts and it makes the rituals worse. Then I feel embarrassed after I finally stop repeating whatever it is, I'm doing. I feel like I can't trust anyone, and I’m terrified but I know it's not real. I can't afford to lose it/show it.

I'm really frustrated right now because once again I feel like I can't keep up with my own brain and I just can't keep doing this. I'm so tired of doing this. My head is always going and going and going and I just want to unplug it. It makes me so stressed. It's like I have someone else in my head who won't shut up and is always pointing everything I do out. Like I'm walking on eggshells around myself so I don't trigger these thoughts. But if I walk on egg shells then it just goes on about something else and I feel like I'm going crazy.. I feel so bad because it makes me so snappy. I want to bash my head in because I'm so over it. The only thing I know that helps is anxiety meds, because I had one one time and it actually really helped me (it didn't even do it's job! Because of how bad my anxiety is!! I'm just so desperate at this point for relief) But the last time I brought up going on meds for anxiety with my mom she said I'll get addicted, like my dad, or my grandma, or whoever else in my family because everyone in my family is addicted to SOMETHING. I don't see the issue in trying though. I feel like I'm someone who could really benefit from anxiety meds. I don't talk about my feelings often BECAUSE of anxiety, so it seems like I'm just trying to go on meds for no reason. But it's like..my body hurts. All the time. And my brain never stops. My brain is so messed up. I feel like I could do so much more if I wasn't like this. It's never going away, I've tried and I've tried and I'm still a mess. I just want it to stop. I'm not asking for much. I just want the fear to stop and the intrusive thoughts to stop and the racing thoughts and the feelings of doom and the nervousness and and I actually want to feel okay in my own skin for fucking once. I've tried everything nothing works im losing patience and I'm losing hope. I feel like there's something wrong with me. I feel like my brain is broken and that makes me sad to be honest. I feel like everyone around me can work. Why can't my stupid brain work???? I try so hard. I try so hard all the time. And it still doesn't do what it needs to do. I hate myself so much.

For a while now, I've been having trouble concentrating... especially when studying... so I'd play the sound of rain or a forest or something similar to distract myself, and when I'd finish and turn it off... a pile of thoughts would come back to me as if they'd piled up on me!!! Anxiety, rituals... what should I do?
