wish losing weight was quick and easy

Hello People!
My name is Erin. I'm 32 years old and very over weight. You wouldn't suspect it by looking at me, but standing 6'5" tall and 245 lbs would shock the hell out of you.
I've tried every single diet out there and so far nothing worked....I was doing the biggest loser at work and lost 12 lbs last fall. By the time the holidays hit I gained every single pound back and more...that was depressing.

So here I am, needing desperately to lose this weight, more like 30 lbs. I don't even know where to start.

So far my motivation is my awesome dog, he needs to lose some poundage too. Oh and my sister's wedding in October.

Any info would help me out....don't be shy to hit me up. Be warned I use humor a lot and make fun of my self on a daily basis. It's just one of those things to help me cope through this weight loss....
