There is NOTHING wrong with taking a break for a little bit... It will take the heat off, and help you see things in your life in a different perspective. It sounds like your being a little more careless than you would normally be... Once you get everything back in order, come back to cannabis! I've quit and came back to pot prolly 10 times during my "cannabis career"... Sometimes for a couple weeks, sometimes for a couple years! Always quiting and restarting for different reasons...
I guess what I'm trying to say is, pot is supposed to be an enjoyable part of your lifestyle. If it's becoming unenjoyable, take a break and come back when it can be fun again!
