Damn dude, I (truly) feel for you. It's increasingly rare for me too, but it's so healing. If you're comfortable sharing, whereabouts do you live? What are your political inclinations? (The latter I ask because it radically influences what you find funny, not because it matters otherwise).

With no context, I highly recommend finding a comedy club near you and having a few drinks. It might take several attempts though so don't give up
