I suggest simply letting it out, it's not only unhealthy to keep your feelings locked inside, but from what I have heard and read it's actually healthy to cry and let out those emotions!
In answer to your 3 sub questions..
1. Yes I feel it quite often due to my own issues in life. (You are not alone!)
2. I cry when and if I can. Sometimes I say to myself all my tears are long gone. But there's always a good cry left in me, you just need to find the best way to let it out. Talking to a friend, or a trusted family member ect. ( Not specifically crying but finding a way to let out emotions that have been building up is an important part of healthy life.)
3. I cry.0THIS IS NOT RELEVANT ANYMORE
