Honestly, ive lost a lot of friends, some who left me and some who I left and a one friend that died at 16.
And recently I feel myself too lonely, even online which is weird, it never occurred to me how lonely I feel until now, no messages from anyone, just notifications from gmail and YouTube videos..
Im a really social guy but even when I socialize with strangers like for example being at parties or playing games I will still be lonely at the end.
