Yes, exactly. I have exercised daily (either weight training or cardio) for nearly 20 years. I've also had anxiety and depression for that entire stretch of time.

Exercise was how I stayed mildly sane for a good majority of those years, but when I started taking medication it was like the entire world changed. I wish I had started earlier in life. It helped me to become a lot more introspective as well, being able to better examine why I was feeling the way I did.

There are some things that no amount of exercise or "healthy living" can fix, that's unfortunately just the human condition. It's nothing to be ashamed of.
