Hey Debbie! First of all: I wish you luck in your treatments, you seem determined and strong so I have total faith that you can beat it.
As for weight loss/getting healthy, we've got the exact same goal. I'd love to work with you and keep in touch with you on here. Selfishly: I do best at losing weight when I've got friends (as they all say) but I like to have friends online, not at the gym. Being at the gym is "me time." Anyhow, if you're interested, let me know! My story is under the thread titled "Newbie from SoCal!"
And hang in there! The best thing is that you're choosing to work towards your health and that will help you in the end. You'll beat this.
