I'm familiar with your
Online Journal and had wondered where you disappeared to. Your post helps me understand it.
I'll be perfectly blunt, your motivation has to come from within. Sure we can give you a raw-raw like we like to do, but you've been here long enough that you know exactly what you need to do. I'm guessing that at this point you just don't want it bad enough. So you'll just need to stay where you are at, perhaps sliding a little more until you hit your "rock bottom" of disgust with how you look and how you feel. You may need to pack on another 25-50 lbs. before you get to that point. "Rock bottom" is such an individual thing.
Rock bottom is the beginning of great things happening, because you become sick and tired of being sick and tired and become disgusted with yourself in such a way that you tell yourself that you've had it - no more - things will change as in right now. You take ownership of your situation and, fueled by a strong desire for serious change, do something about it right now. You'll be able to do it when you want to.
To speed up you hitting rock bottom here's my suggestion. Go into your bathroom or bedroom where you have a full-length mirror. Strip down butt-naked and with a hand-mirror turn around with your back to the full-length mirror. Now take a look at your behind looking at the hand-held mirror. Rotate and see yourself from rear, side, front and other side. Ask yourself if you are happy with how you look. Maybe even squat down and take a look at yourself from that position. That will do wonders. Watch your fat jiggle up and down, left and right as you do so. Do this over and over as long as necessary until you get absolutely disgusted with yourself to the level that you hit your rock bottom, saying enough is enough, and look yourself in the mirror and say "no more, things are going to change right now, it's my responsibility and nobody else".
Then get with it, resume your online journal, train hard, knowing that we will all support you in any way we can.
