Welcome to 3FC =)
You've found a site full of members who know what you're going through. Who know what it's like to want to lose weight, to need to make changes, stick with them, and keep going forward no matter what.
You're not alone.
If you're depressed, are you speaking to anyone about it? You might find some insight from those under the Depression and Weight Issues area.
We'd absolutely love to lend a hand or an ear.
You don't have to find a "diet" so much as you have to start making changes. Some people can make a whole bunch of changes at once. Others need to make them one at a time. There's nothing wrong with either way... as long as you're committed.
You can do this =) Hope to see you around the boards!
