I hit 300lbs this week and I'm so sick of it!

I've decided to go back on my diet of choice, isagenix. I have had a lot of things go down in my life recently. Since I got married in mid July I have gained about 60lbs! I didn't even think that was possible! Since I'm going back on the full plan I have come to the decision that I have to get my weight under control before I start actively TTC ing again. I'm no good to anyone if I'm sick and fat. I'm going to be 33 in April so this decision is hard to make, but I have to choose me first! Anyone else in the same boat or have any words of encouragement? I can surely use it!
