Something else which helped me when i would worry about other ppl is that i would get a piece of paper and write down everything that could possibly happen if i offended someone with something i did or set a bad impression. the conclusion i would come to is at the worst it would be embarassing. nothing serious would actually happen. i wouldnt die or be harmed in any way.
u need to remember that no one has control over u and the worst thing about worrying about what other ppl think is that u are harming ur own mental health and that if u let it go and become care free then nothing bad is going to happen.
I hope this helped bc this is mainly what i thought which helped me to stop caring about what other ppl think about me (to some extent)
Also, just remember that YOU come first! Place yourself above ANYONE and ANYTHING, except God ofc. But you ultimately need to have self confidence ❤️ hope this helps
