It's high time!

Hi everyone! I'm happy to be here, in that I just decided NOT to undergo a gastric bypass, and give myself another chance. Feeling happy to be exercising again after a 3 year hiatus due to illness. Starting slow with walking. My goal is to lose 55 pounds. I'm a working mom with a great family, all of who are very supportive in my efforts. For me, weight loss represents better health, as I am so uncomfortable in my body right now. I recently recovered from bilateral pulmonary emboli and bilateral DVT'S in my legs. Obesity is a risk factor. I'm ready to change. Please help me.
