Insanity

It's crazy.... I know how to do this...I really do. I've done it before, right so what is the problem?!

I'm holding steady at 215. I just had a major health scare because I went to my DD softball game on a lovely 113 degree day and unable to avoid sitting in the sun drank as much water as I could, while pouring water on myself and DD during field changes...anyways long story short I ended up with what I assumed was Heat Exhaustion. So I pumped the water and tried to stay cool over the next few days but after the third day of such and intense headache and the inability to sleep, which NEVER happens to me, I headed to the DR office. Well my BP was 210/150. He was gravely concerned so he gave me some BP meds and had me lay down until my BP came down, then he sent me home with rest and no heat, not even swimming pool instructions for the weekend. Upon returning to his office on Monday he thought he heard a murmur, something that he had never heard before, and being my Dr for 10 years he sent me to a Cardiologist. I went there on this last Monday. Needless to say I had two weeks of major worrying and a few bouts of crying scared for the unknown, however I'm happy to report that I have a very strong heart with no detectable problems. I follow up with my GP on Tuesday and hopefully he will consider working me off the BP meds since this is probably a result of the heat exhaustion/stroke that I got at the softball game. whew but definitely an eye opener! and I know I MUST get this weight off.
SO what do to? What would be the best way to approach this? I've been considering going off the Atkins because the harder I try to get on board, the faster and harder I fall off.
I've gain great power over the last year because I have discovered and admitted to myself and all that I am a binge eater. I feel that has given me great power because now I recognize when it is happening.
Right now I'm trying to stick with good live foods for my meals, a little something I learned from doing the 21 lbs in 21 days diet. I've been eating lots of fruits and veggies, doing salads for lunch and a light dinner. I need to pick up on exercising again, now that I've been given the all clear to move again... I don't know what to do... what do you think?
