Emotionally healthy men, what do you DO with feelings? I never learned from my family and therapists have been useless.

I hear people talk about processing emotions and I don’t understand what this means. When I look it up on Google or Youtube, there is a lot of woo-woo “law of attraction” stuff. I have always just tried to put them aside since they aren't "real" but I feel like I'm breaking down a lot when I'm alone.
