what should i do

i really hate myself. im 17 and have been dealing with these feelings on and off for years. i compare myself and my life to my friends’, which always leads to me feeling worthless and hopeless; everyone else seems to have it so great, they're all so pretty and genuienly care for eachother. the thing i hate the most is how unnoticeable i seem to be to other people. i guess it's cause im ”boring”, kind of introverted and so on, so i really understand them. at any social events im always just kind of there, people often forget about me. i know its my own fault, and thats what makes me hate myself. i dont know what to do about it, ive already been labeled as a person who people find lame and awkward,

and it feels like it would be hard to get out of that position. i compare myself to others so much, romaticise everyone elses lives to the point that i become miserable and just find my own life worthless. i just want to enjoy like everyone else seems to.
