Hi Imran,
I think joining this site is a great step for you! However, I do think you have a ways to go on your own before you're quite ready to have others help out. I believe, from the limited post you've made, that you have the ability to be self-confident and reach your goals. You remember yourself as someone you liked, and what's even better: you believe you can become someone you like again.
My suggestion for a first step is to come up with some sort of general plan. Like eat dessert only two nights a week. Or switch from white rice to brown rice. Go with diet instead of regular snapple. Something that's a small step towards changing your path and becoming more healthy.
You don't need to "start over" but gear yourself into growing towards the right direction. You'll get there, but it'll take time. Keep a positive outlook, and take it one day at a time!
