Dar Heyratam!

Dashtam fekr mikardam ke life has made it a habit fot me not to be too optimistic about everything.The point is, the very moment that I wanna come to the conclusion that I'm infact very happy and "khoshbakht",and @ the same time ke khodaro bekhateresh shokr mikonam,yechizi mishe,yani mahale taghiri ijad nashe va oon chize khoob will soon be replaced by the original situation with this difference that it puts me in partial cloud of absurd thoughts and ye alame swirling "gonjeshk" on the top of my head like in cartoons!And then I usually tell me self: "Now what do I do?"Chera injoorye,anybody got an idea?
