45-55 year olds

I am new to this website but not to the world of weight loss. I am ready to shed the lbs. again and am looking for friends to help motivate me. I am a 50 year-old stay at home mom with about 50 lbs. to lose. At my heaviest weight a few years ago, I lost about 60 lbs. but put 40 back on within a couple years after that. I then started losing weight again and succeeded in losing another 60 lbs. But again, the weight has crept back on and I'm up 50 lbs. I really need the motivation to get started and to keep going. So, if you're interested, let me know.
