Feeling burned out and left out

Im constantly feeling burned out as i filled my free time with part time work as i have no friends. Going to college and part time work regularly makes me feel burned out but there is no other way for me.im going to this work even on week off which is by choice and of no payment. I tried to go to beach , cinema , malls in chennai alone but it never worked. I always felt left out seeing other gangs and groups of friends.i have fomo on seeing instagram stories like going for trips and all. I couldn't even make one single friend after my breakup which hurts me a lot but she has moved on got committed with someone else and going to hill stations with him. No once calls me , messages me or talks to me! Need some suggestions to come out of this rot life im living. Its either i do work which i dont like or i end up doing nothing and alone in my home. Any offline communities in chennai which helps to cope up with this? Im open to whatever criticisms you say and will improve myself. Need a step by step guidance and im tired of being lonely.
