PLEASE HELP!

I gave up drugs (weed, coke, E, speed) over 15 years ago, plus quit smoking almost 5 years ago..yet I am having the most intense cravings of my life I have never had cravings like it, not even in the early days of stopping the drugs.

I am uncovering some very deep and painful stuff in therapy, and I know its all related, and I know too that it will pass. But I am worried right now, can someone please give me some words of advice/support?
