How I am, is it normal ?

I get obsessed with the tiniest things because I over think things, people tell me. I have anxiety but I don't take medicine I would say its bad because I cry because I get so attached to a thought a lot and I can't stop thinking about if I messed up on something it will literally haunt me for months and make me think I'm a bad person, my family is well off and I guess big money and having the most successful lawyer in town is a big you know thing to live up to, would you feel this way ? What should I try to calm down or whatever would help
