How to stop thinking in terms of other people? How to be unbothered?

Problem/Goal: I'm an overthinker at sobrang sensitive pero people-pleaser. Instinctively na naiisip ko kung anong masasabi ng ibang tao. Ayoko naman maging ganito pero grabe ang pag overthink ko na naaapektuhan na ako nito mentally. Parang naiiyak na ako minsan. Hindi ko naman ginugusto pero I'm working on it naman. Ayoko lang sigurong may magalit sa akin or awayin ako kasi yun yung nakakatrigger ng sadness at anxiety ko. Pero gusto ko na talagang mabago to.

Context: In terms ito sa school madalas, alam ko namang iba-iba ang personality ng bawat isa at ayokong may makaalitan rin. Pero hindi talaga maiwasan eh, oftentimes I disappoint people. Siguro dahil sa low self-esteem ko rin at incompetence. Parang na disappoint ko sila eh. Ayaw ko na talaga. Sana hindi na lang ako nakipagfriends kahit kanino. I'm tired of disappointing people at iniisip palagi kung anong masasabi nila. I wish I was okay and comfortable with being invisible. Akala ko talaga magbabago na to sa pag college ko pero I'm encountering the same problems I had when I was still in highschool. How I wish I was okay to mess up at hindi magregret na baka anong masabi ng iba.

Previous Attempts: I don't really have any previous attempt on this kasi, I don't know, I want a way out. Gusto kong magtransfer ng block, restart and reinvent myself. It's what my heart desires eh. Gusto kong mag restart ng life – lowkey. Yung tipong small circle of friend lang at walang drama. Maybe ako lang tong nag ooverthink. Hindi naman ako relevant sa kanila. Hindi naman sila relevant dapat sa akin. Pero bakit naaapektuhan pa rin ako kahit sa isang facial expression of disappointment? How do you grow up from this?
