Help!

Help! I've fallen (off the wagon) and I can't get back on.
My diet is so bad. Mom made lasagna for my sisters birthday... And I ate it :(
my pants don't feel so lose any more - at least I can still zip and button.
The lasagna isn't the only slip. Desert at mimi's restaurant on my anniversary, cake, salami.
I am sitting watching Rileys gymnastics class and typing this on my iphone. Before this I was grocery shopping and I consciously only bought good veggies, yogurt nonfat milk ,healthy nuts, celery. I haven't had a great summer as far as fitness and weightloss is concerned.
I was hoping to finish my weigh loss by autumn- but I've slowly gained Back 10 lbs. that I've already lost...so now I get to lose those again. -joy.
Last summer I was so successful. I was okay logging so many hours away from my family. I felt that it was necessary because my health was in jeopardy if I didn't go out and exercise. I rarely ate with them --I had my nutriton plan and I'd cook meals for my family but I'd go out the door on my bike once they were fed....and if I didnt get in a bike everyday I'd do atleast 30 min walk or stepper.
Last year was about me getting healthy. This year has naturally reverted back to them. A few times I've gotten home from work thinking about going on a ride...and the moment I walk on I hear,"oh good Moms home - mom can we_____." of course my plans are forgotten because I've already missed them all day long. I feel guilty if I leave them home and go exercise. Now it's almost the end of summer and I am still wanting to be a changed person...it is really easy to eat correctly if I'm exercising 1-2 hours each day. I remember how I'd feel after a hard workout ..I didn't want to ruin it by eatting bad. I would've done all that work for nothin'.

Now I need balance! The only thing I've managed is lap swimming class twice a week for an hour and I really like it.

I'm listening to John Mayer free falling, and watching Riley do split leaps -she can't get the arm swing right, I just told her that I could've done that one better. (I could have too)
she's such a strong girl...but she doesn't always get the graceful part...has to be reminded to point her toes..
I love watching her- it's amazing the things she can do. But not today...she's flopping around and not focusing. A few months ago she was on the verge on moving up to level 3 and at every class she was super good. Now she made it to level 3 and it's alot larder than level 2. And it's twice as much gym time(3 hrs per week). Not sure how well adjust once school starts and girlscouts & catch are back...and homework. I've been wanting to take Liam to karate again.
For the last month both kids have been in swimming lessons, 1 hour each day. Monday thru Thursday. Plus Riley's 1 &1/2 hr gnastics twice a week. (and dont forget I work full time)-So we've been busy. -I guess you can see how little time I have had for my own activities.
I know this Blog post sounds like I'm complaining --or making excuses. I really do like keeping my kids busy. It's important for them to not spend the whole day in front of the computer, tv & video games.
Right now I'm trying to psych myself up for a long bikeride this evening - and since my husband is resting before work the kids will most likely be in front of the tv if I go...I think I should rename this the-busy-mom-blog or the-not-every-mom-can-do-everything-blog
