Please help figure out if i have a medical disorder?

i am a girl whos 16 years old with depression. now i keep on worrying i have something else going on too. i don't know what it is or if it is just a habit but i really have been getting very stressed out about making this face that i always have ever since i was little. i squint my face and i do it so often. i think it might be a mild form of tourettes but i have no idea. i have trouble interacting sometimes too and often seperate myself from everyone or turn my phone on silent so i don't have to talk to people. i find it easy to interact with my dog.
