Unable to socialize

Hii im 19(F). And currently pursuing a btech degree from a well known college. And i find it very difficult to get along with people, sem one is kinda over and i still don't have anyone I can call friends. Im struggling a lot to fit in and somehow be like normal people but I simply can't,, idk what's wrong with me exactly, But when I try to figure out things looking at all my past experiences and all I think I've always been like this.. im only comfortable around my parents and two friends that I have from school , baki elleverdem munnil njn very pretentious aayt aan nilkunne ,, enikk ee social situations vayangaraa anxiety undakkunna karyam aann like njn pothuve angne samsarikkar illa appo athond ellrum enne patti enthelum karuthumo ennoke enikk thonnum.. I think people view me as an awkward person because njn aarodum angne pettan onnum close aavoola idont even know why .....i want to socialize but njn uddeshikkunna pole enikk social situations navigate cheyyan pattunnilla despite trying hard ,, I often come across as a cold and weird person.. adyam okke njn karuthi im an introvert but then when i tried to understand it more I think I'm not an introvert because introverts choose to be alone but ente case il I just end up being alone while wanting to have people talk to me ,, enikk ariyuka polum illa ente situation engne maryadakk explain cheyya nn ,I feel like I am watching social interactions rather than being a part of it ellavarkum effortlessly pattunna karyangal ethre effort edthittum enikk pattunnila,, How can I get thru this and get a life i wish to have .
