, I'd like to point you to the Relapse sticky in maintainers first:

Second, I would suggest getting back to basics, weighing, measuring, counting. It sounds like when you change your job things will be better for you.
As for what is the point.....well, you haven't gained it all back yet.....and even if you have, we are always a work in progress....I know I figure things out as I go and learn and try to do different/better, etc.....what is the point? The point is that YOU deserve to be healthy and to feel good about yourself.
