I had no friends at all either.
Since the quarantine and covid started I stopped communicating with anyone.
At some point I just got really depressed.
But after half a year or so I decided I had to do something about it, so I started looking for my friends on dating sites.
I will tell you that it is quite realistic to find friends on dating sites.
So my advice to you, stop being sad and start doing something about it.
I can advise you an excellent dating site where I myself sit.
