Welcome, nomoxcuses (great handle, BTW). You've found one of the best sources of diet advice and support around, internet or otherwise.
You've surmounted the first hurdle--deciding to start. One "mind game" that has sometimes helped me is to change my self-talk from "I have to lose weight" to "I want to lose weight". Somehow it made me not resent myself as much, if that makes any sense.
One of the things that helped me most was to create an eating plan that is sustainable for the long term. Two mind-sets that are damaging (in my opinion) are "I have to deprive myself all the time" and "Everything I eat has to be low-fat". For me, at least, that was a recipe for failure and disappointment. One of the things I discovered is that my body can't handle a low-fat diet. I think many women are in the same boat.
It's taken me just short of two years to go from a BMI of 43.3 to 24.8, and I'm nearly at my goal. During that time, I've learned a lot about what it will take to maintain my new weight (there could be a whole new set of challenges there). Once you start your journey, there will be triumphs and setbacks along the way, but you can do it.
Read some of the success stories of people such as rockinrobin, guamvixen, Glory87, saef, shmead, ncuneo, and Lori Bell (not intending to slight anyone else). There's a lot of encouragement and inspiration to be found.
Best wishes!
