I can’t stop!

so i have tik tok and i comment on videos sometimes. well some random stranger started like arguing and disagreeing with me about something in the comments and every time something like this happens it affects me so much and i don’t know why. like i feel sick and like i’m an awful person and idk why it makes me feel like this. like i don’t even know this person. has anyone else had similar experiences? idk what to do

I am in the uk and voting just happened. My friend of 4 years voted for the party that has the opposite values of what my partner voted. Most people who vote the party my partner voted ARE bad people, but I am an open minded person and willing to know why instead of just assuming someone is bad straight away. My friend saw what my bf voted and was mortified and called him all sorts like racist and sexist etc. yet they haven’t ever had a proper conversation with my boyfriend or really known him. I know that my boyfriend didn’t vote for the reason my friend thought. He explained that he didn’t want the party he voted to win and dislikes them like me. The whole reason he voted is because he knew they WOULDNT win, not because he agreed with them and wanted them to win, he just wanted to lend his vote away and not vote for the same 2 main parties like most people, he didn’t want to vote for the 2 main parties as both of them have failed the country and with the uk you vote for your local politician and in his local area the 2 main parties were close and neither were more likely to win than the other, and he didn’t want to vote for either so he voted for a party that was predicted to be 3rd place and they wouldn’t win which they didn’t, and by voting for the party who were predicted to be 3rd it would show the 2 main local politicians that their seat was not safe and wasn’t a guarantee in the next general election so the vote was a tactical vote for the future as every seat matters to political parties so they would put more effort into making a positive change to secure their seat in the next general election.(sorry for long explanation) I got him to message my friend to have a civil discussion and try and get them to understand that they misunderstood my partner, but they just were not having it and didn’t want to listen and called us all sorts of stuff that we are not and I’ve had to drop them as a friend :( I feel like such a shit person I want to make everyone happy but I can’t and I feel like an awful person because I couldn’t talk to 2 people who disagreed on political party choices. They believe my boyfriend voted the party he did because he is racist etc when actually he tactically voted and DOES NOT support the party he voted, just wanted to take away from the main 2. He has stated that he would be UNHAPPY if the party he voted won, he only voted because he knew there was no chance of them winning. I know that my boyfriend actually has similar views to me and my friend. But he just wanted to try something different and ended up seeming like the main bad people who vote that particular party when he isn’t. Am I worrying about this too much and am I right for dropping my friend who wasn’t willing to have a discussion and has a sort of radicalised view and was rude to us and not willing to listen to my partner explain that they misunderstood?

I am almost 18 right now and when I was 16 and under I did some horrible things I regret and make me feel like a bad person. I won’t go into detail but stuff people would find weird/hate me for. I am quite popular on social media and I see people getting cancelled so much on TikTok for things I used to do. It scares me. I acknowledge that what I did was bad and don’t do it anymore/havent done it again but the things still haunt me :(. I imagine scenarios of being cancelled and being infamous and everybody hating me. The stuff I did was because I was immature/didn’t really know it was wrong but I still feel like such a shitty person. I really want to be a good person and try to and whenever I try to think “I’m a good person” my ocd cancels it by reminding me of all the stuff I have done and I can’t call myself a good person. It also affects my boyfriend as well and my ocd latches onto him being imperfect. He has done things wrong/ things that have upset me, but my ocd takes this and uses it to show me “he’s a bad person” and we are both “problematic” I’m currently obsessing over it.
