Sorry :/

Hello and firstly I am sorry I haven't blogged for a while. I am back though :)
I haven't really eaten well recently. I went out last night and drank loads of cocktails which are hundreds of calories!! I need to get focused and motivated again starting tomorrow. My boyfriend is going away for a few days so I can really focus being on my own although I am going to miss him a lot. I had a rubbish day yesterday, went shopping for a dress and couldn't find anything that looked nice. I cried on the way home and to make things worse I saw my boyfriends ex girlfriend for the first time and she was so thin. I feel disgusting.
I have Weight Watchers on Wednesday and I have put on a few pounds so need to get back the same or less before weigh in. Anyone got any good diets for quick weight loss?
