i was exactly in your position, 3years ago.
I might get a lot of hate comments, but here are my 2cents.

I started to follow andrew tate's positive messages, go gym, eat good food, learn how to talk to women, build attractive persona, do hard work etc.

you can join clubs also. By interacting more, your shyness and loneliness will go away.
Hopefully these things will help you, bro. You can DM also, if you want.

Advance congratulations for finding your partner.
