It sounds like there's loads of support on here for you, I'm not trying to be personal but how big are you ? Not how big do you think you are, or how big do you feel, but how tall are you, stones and pounds, and dress size.
It's hard when your unhappy about the way you look, (been there done that !) And you sound a bit, dare I say depressed, have you been to the Des ? They might be able to help.
Some on here have offered to go through your diet with you, what about making it a regular thing ? Do you have Skype ? Face to face is sometimes easier, what about starting a diet club on the forum ? I'd sign up for that !
I will say it load (but not proud lol) I'm 5ft2, 13st 11, my new jeans are a size 20, and since getting bear I've lost nearly 2 stone, so I was really pushing the boat, (my personal downfall is coke !) I am possibly the laziest person on the planet, so if you want an ear to moan in, mines usually free.
