Sharing Our Innermost Thoughts

Feeling really low , as a student i don’t have any friends, nobody to talk or share anything, im 22 and feel like a 40 yr old uncle, from past 3 years i have been isolated myself to achieve my goal…but still fail…now after 3 years i realised that i don’t talk to anyone, i actually didn’t have any human interaction, also im lacking in all social things… wether its communication or approaching someone, for me its like I’m in a new world right now, I’m addicted to lonelynes and i don’t like to go out anywhere, I’m not on social media… it.was 5year back when i posted anything or open any social media…and now i don’t know any current trend and such things , i don’t know anything abt current world , nowadays i things everything in deep and feel sad everytime,
I joined a library in hope to get better but there’s no use i still don’t talk to anyone and its been 5 months in library even right now im in library …not even this i cant even face my parents bcs of shame that i didn’t achieved my goal , i let them down …now i thing there’s no purpose of my life…
