Dear weightloss, Hello it's me again

Well, here I am again having fell off the weightloss wagon, AGAIN! Don't get me wrong I lost some weight got lazy, and gained it right back. I joined a gym with a friend back in September and we were all gun ho about working out and dieting. I was going to be her motivator, and vice versa but after the initial month we both fell off and then the holidays came. So the little bit of progress I made went down the drain. So having cursed myself out for not having will power I rejoined the gym (by myself) and have been doing pretty good at working out. But, my problems are as follows 1) Eating too much of the wrong foods and not enough of the right ones 2) Too much sugar 3)Eating late at night, in bed 4) Waiting too long to eat 5)Buffets 6) Setting unrealistic goals(i.e. 30 lbs in a month). I used to watch The Biggest Loser and I convinced myself that if those people could lose all that weight in such a short time then so could I. Well, if I worked out six hours a day and ate lettuce, carrots and celery all day I probably could, but that's not me so I don't watch that show any more because it's just too unrealistic. Truth be told, losing weight is hard. Denying yourself things that are good to you but bad for you is hard. Changing the way you've eaten your whole life is hard. But anything worth having takes hard work and dedication. I am so determined to go from 285 pounds size 22/24 clothes to a size healthier that I have to do what it takes to get there,one pound at a time. I know I have to change so many of my bad habits and it's going to take time,but, I'm in it for the long haul.
