getting back on track

Ok so i started doing all this and in the middle of it i had an attack of tremendous pain!
I have been off track. I found out that I had an internal hernia and had to have surgery. Then after surgery i took my fifth graders to Washington DC and ate enough junk and fast food to kill someone!!!
So I am now starting a new day and getting my eating under control. It also didn't help that i bought that addictive cheese puff popcorn stuff on friday and ate the entire bag OMG what was i thinking? And last night Jon and i feasted on McDonalds! What we NEVER do that!!! So i am uterlly disgusted with myself!
You know how you feel when you eat nothing but crap for days? I feel fat, and greesy and just disgusting. So i woke up this morning determined to get back on track. I had one of those Kashi bars for breakfast! YUMMY!!! and i am getting on track with my water again today.
I HATE that Bloated yucky feeling. I have to admit i got really discouraged when i had to have surgery! I was like...What? I have been doing so well how could something be wrong?
I cannot lose this battle! I can't let food control my life. I don't want to be 300 pounds. I want to feel good, look good, and want to live my life and not be wieghed down and tired. Summer starts for me in a week and 1/2 How can i exercise? any tips... maybe a morning walk with the dog? A swim with my kids, and plenty of bike riding.
