Struggling in college

So I finally joined college after failing jee again in my drop year (87 percentile) It's a tier 3 private engineering college (Bennett) Idk why but I am feeling really lost here I am a 174cm introvert guy and pretty much everyone around me is taller than me My roommate and even classmates don't take me seriously Like they would hold seats for other guys but not me Would rarely talk with me I have to always try to initiate conversation and they would just smile or say hmm If let's say 4 people going to play any game and if there are 5 of us they would ask me to stay behind All this is making me more and more depressed and I don't know how am going to do in these 4 years
