I know how you feel, I have thinning and I am a guy. Young too, medical school soon and I have done A LOT of research on this. Girls do have accidental thinning but theres like a 1% chance that it will make you bald or anything like that. A doctor check up, the start of some topical products (not even oral medications, but shampoos and nutrient topicals), and good diet can be enough to fix hair loss problems like these in women. It is way easier to fix a woman's hair loss than a man's like mine =( Don't panic and simply live one day at a time and talk to your physician (and perhaps specialists if he/she recommends you to one) and you will overcome it. Also just had to say, even though your eyes are covered you are beautiful, didn't even look at the hair for a while.
