Welcome, glad to have you! You will find many here who have a lot in common with you. Start at the beginning and take one step at a time. For many of us, that means figuring out how many calories you need as compared to what you eat now, and start cutting back. Change one thing at a time and stay involved on the forums for support. Looking forward to seeing you continue to post!
And now that you don't have to be perfect, you can be good.
