Hello everyone! I'm a new kid on the block. I'm suffering from obesity hypervenilation. I'm spelling it wrong g I'm sure

I'm on oxygen at a low liter and losing weight slowly. Im 5'11" tall 57 and started at 343 lbs. I'm now at 312 since February of 2012. Its going slowly but its going. My doctor said I need to get to at least 280 to get oxygen removed. Heaven only knows I wish I could cut it away
My blood pressure is now excellent and has taken me off one pill so far. So, now I'm on a journey to lose this weight. Thanks for the ears
