Man alone on hill at night

idk about that one, bottling stuff up is bad

Yeah. For example I've bottled up all my feelings and now I'm breaking :D

Proverbs disagrees.

maybe they were referring to negative stuff like anger or annoyance

A lot of translations have it refer to anger, but the original Hebrew word seems to refer to our spirit/strength. Some also add that the spirit should be "held back until afterward". I could be wrong, but I get the sense this verse is more about how it is unwise to let out your feelings and act on them impulsively without considering the consequences, rather than, say, honestly talking to a close friend about some rough emotional turmoil you've got going on. In other words, don't let yourself be ruled by your emotions, especially in a way that will harm other people. Sometimes they do need to be bottled up/held back so as to not act on impulse. It's healthy to talk about them at the right time, but don't let them direct all your actions. But again, I could be wrong. Correct me if I am.

(OK slight correction: the word can indeed refer to anger.)

Well said.

makes a lot more sense

Possibly, but you believe it goes far deeper.
Man, as the biblical head of the home is also the one, biblically, that the family must look to, within the home for guidance. Children also complain to the parents as we as the wife brings concerns to the man. When men appear weak within a relationship, respect for them diminishes. All should give their problems to God but the man must. It has also been said that we should not share our thoughts, our dreams too quickly lest someone belittle something in it's preliminary or infant stage and kill something that could work out with enough study and research. This is true regardless of spiritual affiliation.

I so dislike auto fill and auto incorrect..it should read.. but I believe..

that also makes sense
