can you go to the gym at weird times, like early morning or the late evening?
if it makes you feel any better, most of the people at my gym don't look like beautiful chads and staceys. it's mostly older men and women who are focused on themselves. people only notice you if you stink really badly. people just want to listen to their music.
i feel the same way about my acne scars, but i've been going to the gym, and the more i go, the less awkward i feel. i know it's silly, but i've been wearing eyeliner+mascara, in addition to translucent powder+sunscreen just so i don't feel totally ugly. but i used to not be able to go outside without FULL MAKEUP, like foundation, concealer, eyeshadow, lipstick, etc. but now i feel like there's a huge weight off my back now that i don't have to wear so much makeup outside.
best of luck, anon <3
