Good for you.
And you know what? I've been there... or at least in similar situations. Rock bottom basically. And from that I've learned taking control of one thing (food/eating right) is a step in the right direction and a lot of things seem to fall in behind it.
Something to do with cosmic alignment? Who knows.
But, as someone said above.... don't let this make you into a food/control freak. Life is about balance.... finding a GOOD one.... and maintaining it. Throwing yourself onto the opposite end of the spectrum is going to just make things worse. Find your balance... your inner chi.... or whatever.... and I think everything else good will find you too.
