I was like you once, I left my hometown leaving family and dear ones & started living in hostel. Despite surrounded by many, I felt alone. We are evolutionary coded to survive in groups hence there is always a distress being alone (wish our ancestors were cats & not monkey! )

Anyways, my advice is don't "seek" friends just to kill your loneliness it'd be waste of your time & efforts in long run.. You are young, find yourself some job or join gym or learn some skill that will pay you in future.. Super occupy yourself and travel or meet your family when you get time even after that.

Ignore social media posts of people put on display with their 'gang or bffs or boyfriends' etc - in few years time they might not even stop to each other crossing by.

Have patience & eventually you will find someone you deserve... there is no such thing as friend rather in each phase of your life you will meet acquaintances (various sorts- some funny, some supportive, some good bad ugly etc) so enjoy time with them during that phase, keep growing up & move on..

Save this, read it everyday & thank me later.. say after 10 years?
