Exercise matters for your mental health, not just looking good or longevity.
It’s a bit abstract, but…
If something feels off or wrong, trust your instinct.
You don’t have to.
Anything really. No matter what your friends say, what your family says, you’re not obligated to live your life in a way which is not comfortable for you. Or put yourself into situations you dislike just to please other’s expectations.
Do it your way. Do your best to be a good person of course (according to whichever moral standard you hold). But do it your way.
Moisturizer will prevent a lot of face blemishes.
Hormone related acne changes aside, if don’t have other skin / health issues and you’re regularly changing your sheets and clothes, moisturizing will solve a lot of face stuff.
