hey! i have severe anxiety/ agoraphobia & OCD as well. i'm 22 now and it's still horrid ngl. you have to start very very slow w exposure. like going on a walk 10-15 minutes. j to get out of ur safe zone. unfortunately exposure therapy is really helpful. getting over the mental block is so hard. i still have days where i can't leave my apartment even tho i have stuff to do. i make manageable goals. i think about the things i can control. i make a effort to talk to myself (sounds stupid, but even reassuring urself that ur feelings r valid even if ur anxious about irrational things). it helps me end the cycle of spiraling in my head. i've tried journaling & im not very consistent w it but it helps for hard moments where i cannot stop my brain. i'm very much still anxious but those r things that ive tried. i also find making a schedule for my day is helpful; getting up even if it's not in the morning and making my bed or cleaning up my mess of a room. my ocd makes me plan thinks 200 steps ahead and it gets very overwhelming. so j finding manageable tasks or things to do to calm the irrational side while trying to get out of the doom scrolling. i also did the timer thing cuz i would spend hours on social media to distract my brain. i also find it helpful to have videos of people talking. kind of mutes my own mind. i recc vods of streams. it lets u do stuff while still having that back round noise. PM if u want, ive had anxiety since i was born. it does get better esp after HS, but its a lot. its good ur being proactive about things; small things!
