Fuck drinking.
Get a job with a lot of people about the same age as you, take nootropic drugs or pharma to deal with your anxiety, and then after that start making social medias, following your friends that you make on these social medias, follow their friends and if they ask who you are, tell them.
Eventually through friends and friends of friends you meet up naturally, social events start rolling in, or book an airbnb and host a house party yourself, with the friends you become close with start doing simple shit like golf, or just going on drives or some shit.
This is the only way to get a gf too btw don't believe in this cold approach shit you're not a fucking salesman.
Use that tiktok as an aura magnet, and start posting pics on Instagram, if your Instagram is dry asf just bot a few followers, buy a blue checkmark, maybe bot some of the likes on your first few pictures, don't hide the likes, get your status up
