Like irl isolation or completely? If you’re completely isolated maybe join a discord server or online group and start a brief chat with people or ask for help with a game or something and branch out from there? Irl isolation is a bit trickier but maybe get in a club/job/do volunteer work where it forces you to interact with others? It might sound daunting but it will guarantee that you at least speak to someone
Honestly i was isolated for a few years and what pulled me out of that fast was getting a job, if u can ask your family or friends or siblings to hook u up it gets easier. It sounds really annoying cus working is just bleh but when you drink alot of coffee or matcha (plus excuse to get a tasty drink) then it gets fun because you just want to get shit done, plus it makes u feel more responsible

I’m genuinely very isolated and I don’t know how to start my life najsusjwja (I’m a NEET) I need help/support.
