Okay....a little help maybe?

So, I smoked weed for the first time last friday. Well, low and behold I had a piss test monday morning.
Hooray for me...
It was only the tail end of a bowl, meaning the weed was already burned when I took the hit. I got a headache from the weed and was very tired. After I got done walking my dogs on the beach I passed out for four hours and then woke up to go to a buddy of mine's show.
Saturday I still wasn't feeling too good but ended up staying up until four sunday morning cleaning.
Long story short, it was hot all weekend I ended up sweating a lot and the day of the test we had to pt so I ended up sweating even more.
I drank a lot of water and lemonade and tea.
Will I be ok? Or is this pretty much the end.
Oh I'm 5'7" and 165 with a pretty good metabolism.

Can anyone help me out? Please? I'm freaking out and driving my husband nuts with all of this.
