Best bet is to face the music and deal with the situation. Find out what the scales say, then you can deal with it and move on (and find out what your C has to say). But going to class will help with getting that control back of the sitation and the social support from the group may be an additional motivation. Good luck, remember not the end of the world as long as you admit you struggling and find ways to manage it. Your weight can easily come off if you have put any on X
Oh, yeah to help my friend she got people to donate to Myton Hospice if she losses half a stone in 4 weeks - these helped keep going as it was not just for her but also something beneficial as well.
