Ursula -
You know, none of us can at this point change where we're starting. The time where that might have been changed has passed. HOWEVER, we CAN change what we do from here.
In my experience, it is at best useless, and at worst destructive, to beat ourselves up over what is past. Your choice moving forward is to be the best you that you can be, or to not. It sounds like you're on your way to making the right choices! But I've been here a while...a LONG while...and I'll tell you that the people who succeed are those who let go of where they've BEEN and whatever mistakes they've made, and move forward. So I'd encourage you to try to do so.
We have lots of forums - by age range, by eating plan, etc. Look around, jump on in, and keep posting. Can't wait to get to know you better!
