I don’t know what to do..

I’m genuinely stuck in a rut. I have friends but all of them have lives and just don’t have time to spend together anymore. I mean hell we live in the same house and I still rarely get to spend time with any of them. On top of that I don’t have any idea where to even go to meet people. I’m 20m so that kinda limits where I can go and what I can do I feel. And even when I do go to any place that could be “social” it’s full of people who already know eachother in groups talking to one another. I’ve just been struggling with loneliness and honestly my heart has just been dying for some sort of connection. All of the people I’ve romantically talked to over the last year have all now exited my life for one reason or another. I feel so trapped in the endless cycle of happy at work and talking to people and then the second I walk through my door or the weekend hits and I have nothing to do and no one to talk to or spend time with having meaningful interaction. This all kinda just feels like a rant but does anyone have any idea what to do? Like any advise at all? I feel so incredibly lost.
