My weight battle

Alright ladies, as much as I hate to admit this, I think it's time :(

I have a major problem with my weight right now. I mean I don't hate myself for being the size I am, but I'm just not happy. I'm so tired of thinking my friends are the same size as me only to find out they are a size four while lucky me is an 11. And what hurts even more is the fact that they can sit there and brag about their weight and size right in front of me not even realizing that they are a lot smaller than me. And then what is even worse is when they call themselves fat and they clearly are not so I'm sitting here thinking what do you think about me. My moms co-worker is a 50 year old wanna-be teenager who is anorexic and bulimic and I stay on her about eating all the time, but she hit a nerve the other day about herself being fat and she couldt eat one freaking m&m because she was sooo fat already. I went off. I asked her how she thought she made others feel and told her that if she couldnt eat an m&m for it making her fat that I must need to completly stop eating myself for a month because apparently I was an ox. She was like no, no, no, but people don't realize how it makes others feel. And just when I thought I was losing weight because I had cut back and was din Zumba and playing tennis,my best friend kind of bailed on me and we stopped playing tennis and when I took my pictures for fashion Friday the other day I wanted to cry. I looked pregnant. I know you will probably go look at that post and say no maam you are blind, but I only posted the better pictures of the bunch and I cropped the cute face one because I had an embarrassing gut in it. After that I decided to get on the scale. At the start of watching my foods I weighed 150 and I made it down to 136 in one month. After taking those pictures I got on the scale because I was so unhappy and OMG 158. :( For the past few weeks I have been watching my calorie intake and eating light. My mom also jumped on the bandwagon. I've been eating lots of fruits instead of junk food and picking salads over fries at rsturaunts. I hope I start nocking this weight off. I want to be happy with myself. I don't care to be a size 2 or anything, I would be happy with a 7. I just want to have a little confidence and not feel like I have to wear heels just to make me have confidence.

On to a positive note, I really want one of the one piece bathing suits with the open sides and back. Or a new bathing suit because out of the bazillion bathing suits I have none of them are hitting the spot. Any suggestions?
