A chance...

An opportunity has been given to me. To be a Plus-size model, actually a spokesperson for a plus-size clothing company. An amazing opportunity, problem is I'm not plus size anymore, I've been losing weight, not on purpose, but mainly because of stress and lack of money to buy food that I actually enjoy.
I submitted myself awhile ago, to this model search, and they asked me to come to the event, and walk the runway, have photos taken, etc.
Now if I actually got this, it would be a huge opportunity for my family and I.
But there's no guarantee that I would definitely win this amazing title, of being the company's spokesperson. I have pretty much till the end of the month, to go up a couple of sizes. And no, I wouldn't be gorging on food. Actually I don't know how I'd do it, I'd probably just start eating things I like again.
Dave wants me to do this really badly. Another thing is I would be traveling a lot, which to me is a downside because of my kids.
He thinks I could win this. I want to believe I could.
What do you guys think I should do.
Because I actually make more money being plus-size than I ever seem to make being thin. I don't know why, but unless I'm size 00 again, or a size 16, no one wants me when I'm somewhere in between. It's very bizarre. Extremes always sell.
Please let me know what you think.

I'll be looking forward to hearing from you.
