Need some professional advice to seriously help me out!

OK...I have posted on here many a time but I really have had enough now of not seeing any results with my weightloss! I seriously do NOT need to lose alot of weight, I purely want to lose about 8lbs and thats it! I am 5ft4, I weight 118lbs and even though it may be classed as a healthy weight...I feel uncomfortable! I do have eating disorders and trying to keep binge eating at bay but its destroying all chances of losing this 8lbs! I did weigh 96lbs 2 years ago after a relationship break up, since then my body has just not been the same! I havent had a period for 2 years and this is currently being looked into with a specialist, I feel that not having periods is messing me up...surely my hormones are in a bad way and Im wondering if this is causing weight gain? Also seriously worried about other health issues, osteoporisis etc...has this hapenned to anyone else where periods have stopped? What did the doctor do for you?

Well a few weeks ago I controlled my calories at approx 1500 a day, I walked for 7 miles a day in about 1hr 45, my foods consisted of porridge with water, fat free cottage cheese, huge greenleaf salads with those innocent pot veggies, blueberries, apples, grapefruit etc ... super healthy Id say. BUT...no weight loss and beleive it or not some days I actually felt bigger!!!! Feel like Im retaining alot of water, also I dont seem to be toning up ;( just feel fat, wobbly and water retained ;( also days of no energy and to top that my knees seem to be swelling up and aching!!! Oh what a mess Im in lol! PLEASE please can someone advise me on a diet/exercise plan where I WILL lose 1lb a week! Ive tried appetite suppressants/phenphedrine but even that doesnt work!

Its day 1 today, off to have my porridge in a bit so please advise me on my plans for the day
