How do you manage your mental health?

Exercise and balance. I'm very ambitious but I try to remember that relaxation time is as or more important than the time I work. Also, I was recently reminded by this article that there's a difference between rest and recovery:

For instance, sometimes even when you're really tired, finding time to write can be more healing than just doing nothing (even if sometimes you need to just do nothing).

But maybe most importantly I've really realized that as much as I want to achieve more, that my relationships and extra-curricular activities really are more important to me than my achievements. It's kinda a hard thing to admit. I try to keep achievement in the right context, lest it become an addiction.

Excercise, finding purpose, starting early to allow chill time in the evening, travelling and changing your work environment from time to time I find are key. Agree with @MentalFlaw social media is so so damaging

I cut notifications where I know they are not useful for me. Also don’t use social media at all. Unless it’s work related. This helped me dramatically
