I signed up to my local gym a few days ago, so paid in full. Now I'm thinking of a million ways to back out 
Im almost 18 stone. Unbelievably unfit, i can't believe I've let myself get here.
I feel physically sick thinking about it. The judgement, the showers, me collapsing in a sweaty lump on the floor.
I can't think of what to pack in my gym bag. I want to hide, but i can't sit on the sofa and continue the way I am, as much as I'd like to.
The staff seem lovely buuuuttttt feck I'm panicking.
I have to be there at 10.30
