New and hoping for success

Hi! I am a SAHM and not very into taking care of my nutrition and exercise. I have 8yro and 6yro girls that are finally in school full time! So, It's time for me to get back into me. I thought about going back to work, but it isn't the right time. So, to keep from sitting around eating all day I signed up here and joined a class that includes kickboxing and resistance training. It is a 10 week course of 6 days a week. I am concerned I will lose motivation for the class and stop logging my food. So, I am here in the community looking for traces of support and motivation.
