Hmm...poker affecting life outside of poker is never a good sign. Don't let it affect your relationships...that's a definite sign of an even bigger problem. I don't want to sound preachy or anything but it's true.

As for being stuck in 5NL, I will admit, it can drive you nuts. Have you taken a stab at 10NL? Are you beating 5NL? I suggest taking a stab if you're driving yourself nuts with this.
