Welcome back!
I agree wholeheartedly with Carter... there's no place for shame!
In fact, I think the whole process of feeling shame/guilt for anything over one second is evil, and is a large part of why people get fat in the first place. So there.
Be strong in the knowledge that the fastest way to get from Point A to Point B is not always a straight line.
Congrats on your new your new job! This new job sounds like it fits right in with your priorities, and validates your desire to get back to eating healthily and exercising.
Sixty pounds lost? That's amazing, and lots to be proud of... go you!
I think you have much more to celebrate about yourself than to be ashamed for.
