Another 2 kilos

[Snookerwidow]

I went to the dr today because I have a horrible viral induced wheeze. He insisted on weighing me and to my disappointment (but not surprise) I have gained another 2 kilos this year.
I’m over 12 stone now, not good for my short arse frame.
I can’t bloody stick at something long enough to get results. If I don’t see a loss in the first week of a diet, I give up.
How on earth do I change this mindset? I know what to do but I just can’t do it.
