New to this

I am 41 years old and 203 pounds. I never thought I would let myself get to this weight. I have 2 children and work full-time. I had a spinal fusion 10 years ago that has limited my activity to some degree. I have let that be an excuse for too long. I also lost my mom last year to a long terrible battle with COPD. I am an emotional eater so I put on weight during that time aldo. Today I started my lifestyle change with eating a much lower calorie and healthier diet and exercise. Hoping I can find the determination to stick to it.
