Welcome back! If you search for "restart" I'm sure you'll be surprised and maybe comforted by how many of us have fallen off our program and keep trying again.
I think "need a kick in the pants" is another common theme, you're not alone! Reaching out for help is a great first tep, Newleaf's absolutely right, you need decide you're going to do it. You know how to lose weight, this time keep in mind how you're going to make it a lifestyle that you can maintain and keep it off. That's what I'm trying to do, keep focusing on keeping it off.
Best to you
