Hi all - waves tentatively
I'm teetering on the brink of signing up online today, but have realised it means weighing myself for the first time in months... terrified is not too strong a word! I've been telling myself for ages that the numbers don't matter, it's about how my clothes fit, etc. - except the clothes aren't fitting very well anymore... 
The last straw was the other day when I finally went to see my GP about a problem I've had for several months (feels like a lump in my throat lots of the time) and he told me it was probably acid reflux, then patted his (ample) belly with both hands and smiled in a patronising way as he said, "You know, when you're our size, that happens sometimes..."
I could have died right there.
I'm a size 14, pushing 16, and I go to the gym (hard) several times a week, plus an hour of hiking with the dog daily. I really didn't think I looked that bad - I hadn't even taken my coat off, FFS! I've felt ever since like everyone who looks at me is commenting on the fatty waddling down the street... I was so ashamed. 
Weighing in is a total nightmare for me, can affect my mood and self-image for days. I'm dreading it, but also thinking I need to kick myself right in the arse and get going - obviously I have to do something! I was considering meetings as the ultimate arse-kick, but in this mood I honestly think I would walk through the door and burst into tears.
Going to go upstairs and bite the bullet soon, just hoping for a bit of encouragement. You all seem so positive and brave!
