Extremely Stressed Out

I don’t get why my life is always awfully stressful. I don’t think my mind ever had a time where it was completely in relax mode. Don’t get me wrong I know how to have a good time, but the stressful cloud always right above my head. My life has never been an easy path, things hardly ever work the way I want them to work. Every single choice I make have to be carefully calculated but the worst case is they still go wrong. I am constantly worried about many things because I have to otherwise they could become worse than it is. So, I am extremely stressed out, but I try to put a happy face and make rest of the world happy as much to ability I have left in me. But I am getting tired of it, sometimes I feel like go back home, and take time off from everything that I am doing and re-evaluate my life. Then again I am not a kid anymore, I cant run away, I guess I will keep doing what I am doing and keep believing in myself, that someday good will find its path towards me.
