HELP! My lose 2 stone for charity fundraiser - What have I done!!

It has just dawned on me the commitment Ive just made.

I have high blood pressure, diabeties and under active thyroid and tried several programmes without success and for my health alone need to lose the weight.

Im actually stumped were to start on this one. I have my initial weight taken on Saturday and could do with a little direction. ANY advice where to start would be helpful!!!

I dont want to let my charity down, but Im realising now the task ahead.

Someone take me off the ceiling.

PS Sorry for dumping on you guys!

Ok just reread this post now that Ive put my brain back in gear and I must sound like a right nutter.

Seriously let me put this in perspective.

I am due for my initial weigh in and will be walk 30 mins at lunch times.

I have no faith in weight loss programmes due to a run in with Weight Watchers.

Do any of you that could give me any ideas or highlight the downfalls I may encounter starting off. Personal experience is invaluable.

Thank you.
