Action is good, but if the emotional state is too bad, you can't just act your way out of it. You'll just overreach and break down again. You have to metabolize your emotions. For example through grief and acceptance.
I've tried action and many other things for decades. What finally freed me was crying it out for a few weeks, and now I'm fine. Now I can take action to get out of a funk.
I've only learned about this stuff in my late 30s, although I was deeply affected since childhood. I don't think your comment was particulary callous or ignorant. It just scares me when I see actual trauma being trivialized and thrown in with the "usual" stuff that stresses us out and feel a need to point out the difference.
