Does it get better?

I feel like im stuck in a constant loop in life. Nothings working out . Seem to be the backup friend to everyone. Everyone has someone else and they only come to me when others are unavailable. Dont feel like studying even though I wanna do something. Always go alone everywhere. Wanna do research but my profs r of no help . Body dysmorphia hits different everyday. Does it ever get better? This feeling of not belonging?
