loneliness

I've always loved to stay at home, sitting there watching tv, playing online games and snacking, doing all this alone..
Why can't I get to what I was once ?
Now, I seriously hate staying at home, staying at home let me know that, I'm very lonely, alone..
I'm staring blankly now, I feel like going out but going out alone is so not fun..
I feel like playing games, but playing games alone is so not fun..
I've always wanting to go home and switch on my computer to play games but since when did all this changed??
It just changed, without me knowing..
