Struggling with Anxiety and Adulting

Hi! I just turned 22 and am really struggling with this whole adulting thing, my anxiety feels so debilitating, I've been off of medication and haven't seen any doctors for going on 3 and a half years, I know I should go, at least check in, but I've made the appointment and I just end up canceling the day before - I've been learning about myself thanks to tik tok therapy - and I know what most people say "really? your getting your information from tiktok?!" yes, I am and I make sure I double check with research of my own. I'm not sure how this app works yet but I was just hoping to find people going through some of the same things to talk to, covid has made it really hard to make and keep friends so maybe you need a friend too?
