Welcome back Soulful and so so sorry that you have a need to come back.
I actually spent some time in Playa del Carmen years ago. It is a very beautiful place and unfortunately, a great place to be if you have a drug or alcohol problem as your lifestyle blends in with all the tourists whooping it up . . . sigh.
On the positive side, I went to a wonderful AA meeting in Playa del Carmen. By now there may very well be Alanon meetings there too.
Keep taking whatever next right step to get yourself out of this situation. I am so impressed that you have developed an online business. That is amazing!
