Dude, we've all been there. Many times. This game is all about peaks and troughs, you'll pull yourself out of this in no time I'm sure. I'd say I experience the same feeling as you right now at least once every 4-6 weeks. Take a break and step back from this for a week or two, somebody posted recently about taking a break from game, it's a worthwhile exercise to come back feeling refreshed and revitalised.

This is an intensely emotional game we are in so inevitably it is going to be draining at some point. Just chill dude, relax for a little while and come back stronger.
