Can anyone please help me with this situation...I really am miserable..I think I might kill myself?

Ok Im decent looking and so freindly but the people on my course just ignore me they dont invite me to any socials...they dont want share a room when we go on trips...they dont like my statuses and dont ask how I am or anything...theyre freindly and polite...but its been three years and I felt like I havent made any freinds...we are all graduating soon..do you think theyll be more freindly now?
