DIETITIANBECKY has given you GREAT advice :-)
You will find that by using the Nutrition Tracker, and weigh all of your food for increased accuracy, that you will be able to tweak your intake so that you are within the guidelines. When you go to your Dr's appointment, take some random printouts with you to show what you have been doing as well :-)
I can't give you a recommendation re Dr's (live in a different country), but here is a link that you may find helpful: findahealthcenter.hrsa.gov/Search_HCC.aspx
I remember a lot of years ago, before I got married, I wanted to go on The Pill. Back then, it wasn't the done thing for a single woman to take it and it was frowned upon. Some Drs flatly refused to prescribe it unless the woman was married. Anyway, I asked the Receptionist which Dr at the Medical Centre was easier to get it from. They said one Dr, and I didn't really feel the most comfortable with him at the time, so against their advice, went to the other, who was a very devout Christian , and who had been a Missionary in what is now Uganda, and who was dead against that sort of thing . It surprised the pants off the Receptionists when I came out WITH a prescription!
I wish you well in achieving what you are wanting to do. Don't let what happened in the past interfere with your health now! Fortunately, not all people are tarred with the same brush!
