I usually feel better after a cry, like dispelling unwanted energy, especially now as I deem cries as not bad. My three favourite places to cry are: the ocean, the shower, and while driving.
My teenage boys see me cry when they are around. I'm not ashamed to let them. I believe letting them know others get vulnerable and learn how to deal with it, is beneficial for them, especially as they are learning how to come up with strategies in dealing with their own depression and anxiety now and into the rest of their lives... but I completely understand how difficult it is to be open with uncomfortable emotions.
I was on an escalator going down in a shopping centre the other day, looking at another man on the up escalator, thinking hard into his face "What's YOUR reason!? What keeps YOU deciding to keep living each day?" By the time I got to the bottom of the escalator, I'd decided that my purpose in life is to become a better man, keep doing this work, and hopefully let that filter into those around me. Some days are harder than others. It doesn't mean I always feel like I have a reason to live every day. I have to keep doing the work of accompanying neutral or positive mental judgements with my uncomfortable (I won't say 'negative' anymore) emotions. it is my most significant work, and takes great effort and fortitude.
Hope this helps.
