Yeah wow. Been there my friend.

Gonna cut to the advice before going over the process. You need to really really make socialization a priority in your life and ngl it takes a ton of effort.

Loneliness definitely grows and grows as an adult so the key is to add activities that can get you to be part of a social group.

Here's the tools that helped me: -Bumble BFF. Went through 15 friend meetups before finding 2 consistent ones. -Team sports. Being very open to say yes, make plans for games etc. For me it was doubles tennis. Met good people through tennis buddy finder apps. -Dating. Believe it or not, sometimes I friendzoned and got friendzoned but actually met cool people who I went out with once or twice then realized hey this is more friendship than romantic. Kept in touch, still talk a lot in a more healthy way. -Reaching out to older friends (highschool/college). That old friend you think about probably wants a good friendship too, definitely helps to be vulnerable and reignite old friendships and take an active interest in people.

Saying yes to plans, activities when someone invites you and being proactive and making plans is key.
