Hi Forester. Sounds like you have a lot going for you. You will be able to better realize your talents, share your knowledge, and support your children sans booze (though I suspect you already know that). You can free yourself, it just takes some effort!
As an aside, my graduate work involves using fungi to clean up environmental contaminants. I always get excited to hear about others with interest/expertise in mycology!
Best of luck,
Michael
