I've been there.
Firstly, use this space and freedom to get to know yourself, builds skills, learn things, explore life. This has the highest ROI to your success, well-being, and everything else.
Secondly, leave the house, as often as you can. I had times when I didn't have many friends. What I found out years later is that it's quite simple - just don't stay home all the time, lol.
A massive cheatcode is to join sport groups, participate in other activities that interest you, and explore Facebook events (as well as MeetUp, Couchsurfing). Soon you will find likeminded people.
