I dont feel like i am pretty anymore?

like last year and the years before i thought that i was beautiful. people complimented me all the time, i got alot of attention from guys and everything. im still in high school btw( 16 years old) any who, its like my facial structures have changed. i don't get half the complements, and i am starting to think i am ugly. idk, but i guess im maturing? ive been trying all sorts of different make-up, skin creams, and regimens to try and get that look that i once had back. am i crazy? is my perception of myself distorted?
