another thing i meant to comment on: you asked about "what do I look forward to?" and man, i had the exact same thought and bout of depression too really. It was a shitty realization to be like, oh what the heck do i do now. or why do i need to go to work (ha) or mow the effing lawn, when there is no reward!! i went through some lows pondering that same thing.
I will give you two answers - the first is immediate gratification, and that answer for me, at least, is/was food. knowing that i had a solid meal to look forward to, often accompanied by a dessert of some sort. do not be afraid to gain weight, a little weight. it's crazy to think that i justified my addiction by saying "well it keeps my appetite down" and "I'll quit after I lose and keep off 10-15 lbs." well that hadn't happened for years. and i've only gained like 7 lbs. after quitting, so not bad really.
the second answer - I've only had tastes of. short glimpses, but a taste of freedom nonetheless. and I think that part of breaking this addiction and habit is allowing me to notice and savor the smaller moments in life as well. ie - the smell of my wife's hair, the cool breeze in the evening. a cold beer on the patio.
don't lose hope - there will be other, much healthier things to look forward to and anticipate
