i keep seeing posts on tumblr that are like "go outside! exercise! read a book!" but it's often framed in a condescending way by jackasses talking to you like you're a child. i think the advice can be useful though so here's a hopefully non-dickish attempt:
~ exercise is important for mental health and has benefits for anxiety and depression over the long and short term (source). though it's not the end all be all or as effective as therapy and medication, it is true that exercise has physical and psychological benefits.
"but what if exercise is difficult for me?" that's OK! i'm a chronic pain sufferer with back and leg problems, and i use a walker and am in a physical therapy program. it's perfectly fine to exercise for only small periods, and to take as much rest as you need to. exercise when you feel capable of it and don't push yourself. also remember that walking around your house, playing fitness games like ring fit for a few minutes, stretching, and other physical activities are all forms of exercise.
speaking of chronic pain, if you have abnormal pain or discomfort moving or exercising, consider a physical therapist. "abnormal" here does include "i'm 30 years old and i'm in pain all the time" - you shouldn't be, and if you haven't already, that's a concern that you should bring up with a doctor if possible.
