I pick a great time to try running though when it's the wet,cold and windy season
I tell you one thing though, when I was using a gym on a day where everything and everyone was making me upset/angry n'all, I got soooo much motivation and adrenaline that I managed to row and cycle longer than I usually did
Obviously some people are different and channelling all the negative emotions you feel into exercise might not work or be beneficial for people, but that instance it really did for me. I felt so much better afterwards cause I used up all my emotions and got tired really quickly and didn't think about bad things as much
