I get this is unsolicited advice and almost certainly you just wanted to vent and not hear solutions, but I wish someone told me this when I was really lonely.
There’s a group of people nearby that regularly gather to do something you enjoy doing. You must find their bulletin boards, meet-up groups and congregate with them.
Do not go to make friends. Do not go to solve your loneliness. Do not actively avoid making friends, but you must make your intentions clear. You are going to have fun and help others do the same.
Dedicate yourself to this for a year and every problem you have now will be solved.
If you choose not to accept this mission then instead set a reminder in your calendar for a year from now and reach out to me then.
