Fitness Burnout

Options
Okay so I am a Zumba teacher and I teach my classes about three times a week. I also have a personal trainer that I see on my off days twice a week. And then I run on my own at least one more day. I've been keeping up this fitness schedule of working out six days a week for about two months now and I'm starting to get the burnout. I'm bored and not feeling the same motivation I used to. What can I do to not slip backwards? Naturally, I still have to teach Zumba because it's my employment but I find myself wanting to cancel my trainer sometimes and this week I did NOT go for my run... :\
