my braces have changed my face - feeling distresed/sad

i diddnt know where to post this
but ever since i have had my braces off my eyes appear to have gotten smaller there higher up and i have half as much eyelid and i think that their getting worse i also stopped wearing my retainers so i dont know if that has anything to do with it but its making me really sad i dont know how to reverse it and i really want too

im so upset that i cry about it everyday and i think its making me depressed
before i was acctually really pretty and people would tell me this some people even said i should be a model (although im 5/4 so i think that may have been exagerations) i was happy when i looked in the mirror but now i see someone else and its making me really sad im only 17 so my life hasnt even really started i think if i was like 40 i would be able to deal with this better.

im obbsessed wth looking at my reflection hopeing things will get better , but they dont im concidering wearing masquerade masks everyday so that i dont have to see my refletion and can pretend that i look how i used too but i know that would cause interferece with my life, jobs ect...

i dont know who to speak to about this or how to fix it what should i do?
