Trying to Lose

My goal is to lose 20 pounds. I have been married almost 2 years and during that time I have gained over 20 pounds. Exercising is almost nonexistent for me at this point, but I'm planning to change that starting today! I have been having severe lower back pain and I think all the fat I've put on in my belly is my biggest problem with my back. I haven't been happy with myself when I look in the mirror for a while now, but I just kept putting off getting serious about doing anything about it. I'm not very self motivated and I find myself saying "ahh, it's okay I'll walk tomorrow", but the thing is, tomorrow never comes because there is always a tomorrow. I know my goal is fairly high to start out with, but I would like to at least lose 5 pounds in the next month and keep it off. I think 5 pounds would really make a difference in my appearance. I have genetics working against me as well. My paternal side of the family is overweight and because of their weight problem they are all diabetic. I know if I don't do something about my weight now I too will become a diabetic. Anyone is welcome to add me. I welcome support from others and I am better at supporting others than at supporting myself.
