Struggling with feelings

I've never experienced something like this before, mainly because I'm usually isolated and don’t have close friends just one friend online. But recently, I was ignored for no clear reason. I mean, we all have work, studies, and things that keep us busy, but not to the point of cutting off communication entirely or replying after three days with just one message

What bothers me even more is that playing games alone has suddenly become awful. I used to enjoy video games by myself more than anything, but now it just feels empty

I don’t want to fix things or look for new friends. But this feeling really got to me. It's strange because I used to be even more lonely before and somehow everything felt fine back then

How do I cope with this feeling or get over it? Has anyone gone through something similar?
