From your past posts, it doesn't sound like you want to apply for a PharmD starting next year, but rather try to prepare to go to medical school. On top of this, you have researched schools shutting down and have recognized the supply vs demand not playing favoritism to new graduates (with you being a nontraditional student yourself).
That said, with your history in chemistry and degrees outside the U.S., it would be drastically difficult to even try to give any advice on choosing nursing vs pharmacy and which would suit your personality and tolerances (one is nothing like the other). Do you like being on your feet well beyond any 8 hour work day trying to deal with multiple patients in a stress fast paced environment, or do you like dealing with third party insurances with little tech help and hour cut-backs (majority of pharmacy being retail setting)? I would just look at the best and worst case scenarios for each one and then imagine doing those tasks for the next 20+ years.
If your end-sight in nursing (after putting in your time) is to be a nurse practitioner, then I would at least consider that route. If age is not a factor for you and your desire is set to medical school, then do that. No matter your decision, you will have to cough up more money to pursue a career change so in the end, in the next 4-8 years, do you want to be a 45 - 50 year old physician, nurse, or pharmacist?
Whatever your first thought is, do that.
