Losing to gain

My name is Tammy and I am a 35 year mother of two. I am 4'9" and currently weigh in at 166.4 pounds. I live in Mount Joy, Pennsylvania.
I have been told by my doctor I have gained 40 pounds in less than nine months ever since my hip injury. While I cant exercise as I had been doing before my injury, I decided I can at least start with eating better.
Having a bad time with depression after both my first and second opinion doctors told me surgery isnt going to happen to fix my laberal tear. I had resiged to live with the pain and I began eating too much and eating the wrong thing. I even started drinking soda again after two and a half years.
I last saw my doctor on the 25th of April after having to get a recheck of my cholesterol levels that had doubled since last years annual checkup. This caused alarm with my doctor and I worked three months to get it down. She was happy with the results but I wasnt. I used to have a total cholesterol of under 150 and now it over 170.
I decided May was going to be my turn around month. I quit soda cold turkey (again) and tomorrow will be one week. I could use encouraging friends and someone to hold me "accountable" when I mess up. So, while I know it isnt likely I'll find many local pals, I thought I would give it a shot.
