Does anyone else deal with people being incredibly rude and nasty towards them?

It's hard to list every specific example of this happening in one post. Just in general I deal with a lot of people being just so rude and nasty towards me and I don't know why. A lot of customers/clients I deal with at work are so quick to raise their voice at me and start yelling at me over any tiny inconvenience. A lot of my coworkers give me the cold shoulder or make mean faces at me and don't respect me even though I always tried to be respectful of them. I also post fun, non-controversial hobby type of content on youtube now and then but I get these really inflammatory comments with people writing paragraphs just destroying me and tearing me down in every way they can over some really tiny thing they didn't like. I never feel liked or respected or wanted by others, I always feel disrespected and bullied and torn down.

In general I find that almost nobody has any manners or any sense of how to behave or conduct themselves in public and it saddens me. I also often see people driving really dangerously and violently and it's like bro, what is the point. I feel like I have this weight on me daily trying to deal with all of this. It's hard waking up in the morning and knowing it's another day I have to navigate people's rudeness and aggression. Another day of people taking out whatever issues they have on me. I'm always told to "think about other people, they might be having a bad day" but those people never think about me or care if I'm having a bad day. They don't think twice about what I might be going through. There are so many bullies and assholes every day in all shapes and sizes, of any age or gender. It's really hard. I try to be polite and respectful of others but then I ask what's even the point if nobody else has any respect.

I'm wondering if anyone else struggles with this. I think about these things a lot and I'm having a really hard time dealing with it. It's like I'm being constantly torn down and put down to the point where I don't even know who I am anymore. They always say "put yourself out there, what's the worst that could happen" but then I try to put myself out there and people are so harsh and nasty. I am really having a hard time figuring this out, I don't understand how to feel comfortable or okay in this world
