I've been where you are. For me the path out was exercise. Wake up and work out - every day, 7 days a week, first thing after you wake up. "Working out" can mean walking to the end of the block and back. And then you get to think, "Even if I do nothing else of value today, at least I worked out." Do that every day for a month, first thing. If you can ingrain that pattern in your brain, I promise you one block will become two and two will become four. And you will look at the crap you're about to put in your mouth and think, "this is not food." For me that was the path out. There's ways to overcome the women thing - really. And 30 is not too late, not even close to too late.
