Making friends requires repeated, low-stakes, in-person encounters. Humans need time to suss each other out before committing to friendship - are you cool? Trustworthy? Do we have things in common? Share the same sense of humor? Etc.

Brainstorm activities you truly enjoy, not just activities you think you enjoy. They can't involve money or sex, because that stuff's not low-stakes. People need to be able and willing to prioritize friendship, and they won't when that stuff's involved.

Find - or start - a Meetup group or groups around your real interests and commit to regular, scheduled events, like, every Tuesday we do thing X at time Y. Get the regulars to commit to being co-leaders, so the burden (and $25 monthly fee) isn't borne by you alone. Drop people who no-show or last-minute flake more than once. Don't assess the group or groups' results until you've run it for a year or so.

Making friends takes WORK, since you have to overcome the period when it's more uncomfortable to hang out with the person than not. That's why you need some sort of fun event or activity that draws people in and gives them something to do until that stage is past.
