anxiety? introversion? shyness? or

(this wouldn't be the only reason I believe I might have anxiety but I just wanted to talk abt this specific issue) I really struggle with talking to ppl my age, I don't prefer adults since I find them boring I just talk to them easier since I just have to be polite, and it's not like I'm trying to be friends with them. It is hard for me to make friends with others around my age, I have strict parents so I can't say most curse words or talk abt inappropriate subjects, and tbh nor do I ever rlly care to, not that I never cuz I have made jokes once in the blue but I usually like to avoid those things. I also constantly re read what I text someone which takes me long to reply and regret so many things I have done in the past where its come to the point of me no longer wanting to talk or do much so i can avoid embarrassment, i get a headache from how much I am of an overthinker. I also can be hyper sometimes which is too much for people to handle, or i get easily distracted in conversations because my mind is constantly pacing with thoughts. Sometimes I feel like I will never be able to have a close friend, i mean I've gotten used to being alone anyway but sometimes I just wish to have someone else who understood and could be there for me :/
