Out of control & desperate for help :-(

Hi, I've just registered on this forum in a desperate search for some help.

I have a really unhealthy relationship with food. I'm either whiter than white, eating really well and losing weight OR I'm spirallying out of control and eating everything I can lay my hands on. It's like having an internal light that's either on or off, when it's on everything is great and in control (food wise), when it's off, I'm not, but I don't know how to control the switch. If that makes sense :-/

I seek food out, and eat in secret hiding the evidence as I'm embrassed at the amount. I hate being overweight, and it's limiting my life so much. I say no to most invitations because I feel so awful about myself. I know all about the health risks and I'm despreate to be a good role model for my daughter, but I still can't help myself. If I do try and explain it to someone they don't understand, they think it's a simple case of "well, don't eat so much then".

I've made an appointment to see my GP but she can't see me for another month. Is there anywhere else I can go? I don't have loads of money to pay for private sessions.

Yours hopefully x
