Hey there,
Well, deciding to post a thread is a good first step! It tells me that you do have the desire to have a desire, if nothing else.
One thing might be to do some journaling. I don't mean anything fancy, just make a list of all the reasons that you would want to lose weight, and how you feel about each of them. And, you could make a list of all the things that are stopping you, and how you might solve some of them.
Just a few ideas--I'm sure lots of folks here will have other ideas! Basically, becoming more physically active and watching what we eat is the idea.
Good luck!
Jay
