New to MFP-looking for support

Hello, I'm new to MFP. I've used it briefly before and fell off. Now, having gone through a somewhat traumatic experience at home recently, I have been motivated to really get my life on track. One of the biggest things I want to do is lose weight. I was 302 lbs in the summer of 2011. My biggest ever. Now I am 280 but would like to get down to about 225 or less. I'm looking for support and people with similar thinking and goals. Looking forward to this experience. Thanks!
