Do people think I'm pretty?

....you're gorgeous. Like honestly not kidding, freaking gorgeous. You have nothing to worry about. Also psychology shows (I'm a psychology student btw) that if you are down mentally it can bog down your physical health, Stress and depression and things as such mess with your physiology and make you sick, so if you work on your mental health and accept that you are beautiful, which you are, then your physical health will likely improve, however I'm not promising it will get all the way better, just that study shows it's likely to improve.
