My Weak Will

There is no way around this one, I'm fat. I am. At 402lbs I am fat, and scared to death of it. But even still I have a bigger problem.
I am smart. Not a genius, and my common sense sometimes flies away, but I am pretty smart. But I am also weak willed. And it is part of my problem.
I love food to much. I tastes good, well the things I like anyway. And I can't just give it up. Mac and Cheese, chocolate chip cookies, pizza, sushi, hamburgers, hot dogs, I love it all. And all of it slowly killing me.
Last summer I was diagnosed with Supraventrical Tachycardia or SVT. It is a problem with the heart that makes it beat to fast. Which is bad. It shockingly has nothing to do with my weight, yet the added stress doesn't help the problem. And yet it still wasn't enought to get my ass into gear.
As stated in another post I am afraid to die. But I can't just give up my food. I am not strong enough. And to make it worse, I am to lazy to get up and move.
I sit there watching tv, going hey 'I could just fall down and do sit ups as I watch this.' Yet I don't. I don't know why? All I would have to do is roll off the couch and start. But I just don't have the will.
But I went to the doctor's and got the 402 weigh in and got scared. And I did something new.
I asked for help. I know I don't have the strength and will, but with help I can do it. And already I know I have made little changes. Small, but better than before. Instead of cutting out the food, with help I am cutting down the food. Instead of the third helping, my mom will say something and remind me. And my dad sends me annoying reminders during the day.
It is hard, and I am still just starting, and stumbling. But I am doing better. Because I will tell you this, I won't be going early. I don't want to. I like it here to much to leave yet. So let me ask you a favor, if you see me out somewhere eating, stop over say hi and tell me, 'put down the donut,' I will understand and thank you, after all you'd be helping save my life.
