I have to partially agree with razor. Whenever I am feeling down/upset, I always listen to not like emo music, but any type of slow, sad songs and the such. Mostly love songs to be honest, considering that is what makes me depressed.
As soon as I start listening to my playlist, it allows me to visualize and I feel a lot better eventually and am able to go about with my day. I think music is a really big thing, but try it out. For some it just makes everything worse, but personally it makes me feel a lot better - probably because it provides some sort of hope for something working out. I am not sure what your exact problem is, but whatever it is I recommend trying to use music.
Goodluck, P.M. me if you want to ask anything.
