Don't feel bad, once on a whim, I maxed out a credit card by dropping $9k on a new KTM525EXC and then partially out of guilt, sold it 6 months later for $6k... ouch, that still stings when I think about it.

One other tip. If it were me, I'd change you ad some as it sounds too desperate which can cause you issues. For one, they will definitely low ball you b/c it sounds like from your ad that you will take anything and throw in some guns too. Also, some people are just turned off when a seller makes the sale sound desperate. It can give the impression that the bike is so awful that you want to get it off your hands at all costs. I would just list the bike, the basic facts, keep it short and simple, pictures, that's it...
