55 days for weight loss?

So, I’ve been stressing a bunch here lately and have put on quite a bit of weight (currently 207) and my wedding is on April 24th! How much weight do you think I could lose within that time frame? We were recently moved to a place with snow everywhere, I do work out tapes at home but I’m not sure if that’s enough? I would like to look good for my wedding, at least out of the 200’s and am at a loss right now on what to do.

Weight and self image has been something I’ve struggled with for a long time, most of my childhood and my entire teenage years have been a struggle with that, I just turned nineteen so I’m still struggling and trying to overcome it. I was wanting to lose at least 20 to 25lb by my wedding day but I now feel that is unachievable and that I have let myself down. Any tips and tricks to lose weight? At home work outs? I suffer from Agoraphobia, which has held me back on many things in my life therefore the gym is a no-go.
