I think I hate myself more than ever after the ups and downs of having acne.
Why do you hate yourself?
I just feel completely inferior to my friends.
Acne is something that many people growing up experience and is normal. It should not be the cause of feeling inferior to your friends. You should talk with a dermatologist to find a skincare regimen that will eliminate your acne and allow you to respect yourself again.
I know, I just want to use a toothbrush and scrub my face clean.
Acne is often a part of adolescence -- it will pass. You should focus on learning new skills, pursuing your interests, and having fun with friends.
