many of my friends do this, speculating on prices and trade profits. Trading is kinda of a soothing activity at times under stress. Checking out portfolio multiple times a day and just to distract away from problem in hand. 
Well it is good right now but I don't recommend it to be used that way.It might be relieving your stress right now because the market is doing great but once it goes back or the market starts to drop down.
I don't think you could say those words anymore it could be the reason of your sadness and stress instead of relieving you from stress and sadness.
