friends to keep me going

I am new to this part of mfp. I am 41 and trying to lose the weight I have gained. Two years ago I had breast cancer and went through chemo and radiation. Then I had half of my thyroid removed because they were concerned I might have cancer there also. I didn't (thank heavens) but I gained 30 pounds on top of my 40 I already had on. I have lost 25 pounds and I am really trying to eat right and exercise to stay healthy. Thought I would look for people trying to do the same and help eachother to keep it up.
