Due to family ties, I travel to Mexico frequently. My rule in Mexico, since about 2007 (when things drastically got worse), is "nighttime = at home or at hotel". Period, the end.

Some "FYI"

I also carry a large amount of cash ($300) and ONLY cash and my Passport and DL as "walking around" documents. Wallet and credit cards is 1) Home or 2) Hotel safe deposit box.

Your hotel key, you know the little envelope it comes in with your room number? leave it in the room, write your room number on your palm and put key in another pocket not with money. Don't break out the wallet with your Hotel card and room number in plain view to the world unless you want some night visitors.

Most all express kidnappings are done to force you to drain all your ATM cards to the limit, then do it again the next day, to the limit, then maybe one more day.

If they kidnap me with the above items, hey, here is my $300, here, take it, yep I am American, here is my ID if I need it, sorry I can't sh1t an ATM card, have a nice day. They are a little less (a little) likely to harm a gringo.

Do not, repeat, do NOT, carry your fat wallet, stuffed with your five Gold AMEX cards and Platinum mastercard, around the streets nor reach for it when you pay for dinner and the waiter can advise his buddies. No watches either, of any kind.

Also, tone down any associations to big American corporate companies, as they may have kidnap-insurance and thus pay out to the kidnappers. Don't tell the waiter you are a "Piloto" or "Engineer at Exxon" or similar. Blue jeans, low key, low profile. You are on church mission or you are a tourist. Etc.

To the OP, Glad you are ok.

** Mexico has a lot of great things to offer, just "being a secure country" is not high on the list. I feel safer there than I do pumping gas into my car at night near Hobby, however.
