idk but please respond

so i’m going into my freshman year in september... lately i’ve been so weird?? all of my life i’ve always had crushes non stop but i never desired to date anyone. as of like last month or something i’ve been so depressed about me never dating anyone. all of the time i see my friends getting into new relationships and i get so jealous. no one has ever had a crush on me, and if they have then no one has ever confessed it. in my opinion, i’m a pretty good person. i have a funny personality, and i’m not the best looking but i’m definitely not ugly. i just wish i had a boyfriend (or girlfriend, as i’m bisexual) but its so hard to get someone to like me. does anyone have tips?
