I feel ass

Does anyone else feel bad for liking someone?I dont think im attractive enough to like someone, everytime I think of myself in a relationship I cringe and wanna bury myself in the ground, its not like im hideous but im definitely not beautiful. And anytime I like someone whom ive never talked to whether it be a famous person or just someone i see, i feel like im disrespecting them by liking them and i feel like a perv. I just moved to a new school and theres this guy i share a lot of classes with and I think hes handsome but i feel awful. Hes quiet and ive never talked to him i only know some things about him like that he have the same hobby and his name is Leon.
