Sometimes it’s good to have a good ol’ vent and a whine! If you don’t expel that energy it can clog you up and lead to pent up frustration and depression in the long run!
If something is really getting to you, don’t bottle it up. Either constructively deal with whatever it is or go ahead, shout, swear, rant, vent, curse, get it out of your system and once it’s out you will actually get you to a feeling of relief and positive energy much more quickly.
Make sure you use that energy as a avenue to then close the door on what ever it was that got you to that state in the first place.
