Tiring week

The week is not yet over but I'm tired already. Schedule's full this week and I'm dead tired. My feet feels numb and painful. instead of me getting some rest even for a day I haven't or rather the day where I planned to rest got ruined by someone who doesn't act like his age. To make it short he's really an idiot. He's doesn't use that brain. It's really frustrating to deal with him most of the times. I admit I'm to practical but that keeps me sane and feel secure. I've outgrown the days when I don't think or not plan things ahead. Having a safety net or plan b keeps me less stressed because I know there's something I can fall back to.
Times like now,  today,  you have to learn how to control. Less of this, learn to say no. It maybe hard in the beginning but is something that is important to know and do. You can't forever live that way. People aren't always going to be there for you,  maybe that sounds harsh for some but when times get rough those people you call friends will choose what's important to them and chances are you're not on the top of their list.
It's really sad, he's hardworking but he doesn't know how to manage well. More sad, is that I have to deal with it because he doesn't listen. He refuses to listen. 
I pray that it doesn't last long. It adds more to my stress and me closer to death.
