why cant i get motivated,grrr

so i ve been working on my weight loss for a year now. i keepp slipping into periods or zero motivation and once im out of it, its harder to get back in. when logan started school in september i started going to the gym in the morning after i dropped him off. well things happened anywhere from sick kids to me being sick and other obligations. that was weeks ago and so far ive only managed to go to the gym 1 day a week. i didnt go yesterday b/c i wasnt feeling well. i went today, but i didnt finish my ab work out (ty was tired and we needed to go) i could have finished athome but i didnt. bad ash, bad,lol. i am going to go tomarrow, i must. i have like 5 or 6 weeks till i go on vacationa nd i want to loose atleast 10 more lbs. in the paswt year i have lost 50 lbs. that of course includes how much i lost just from giving birth last october. i started loosely following weight watchers ( i should strictly following it) and i started the gym in july. i just really need to stay motivated...
so im going to keep track of myself on here as well.
