Health, fitness and weight loss advice needed?

I'm possibly the most lazy person you'll come across, I have no self control and no motivation, I'm most likely more then two stone over weight and as a female in this culture that matters a lot... Looking at myself in the mirror makes me feel inadequate, I get sort of depressed in a way I guess. But when faced with the option between light exercise or bed, I'd choose to sleep. I recently looked over old photos from 2011 and I had an amazing figure, I'm now 4 dress sizes bigger... All I want to do is cry and sleep. I need a quick fix:(
