With a LOA, I would strongly encourage you to look at what Vocational Schooling(s) you may or may not be leaning towards. After high school, I took some time to work as a welder and made 3x the minimum wage just starting out. What really intrigued me about getting my feet wet with other jobs was seeing how fast time felt. As a welder, I learned how to read and convert units on a blue print and most days went by fast. Once the recession hit back in '08 I figured I might want to spread out and see what else is worth looking into.
The fact is, you have six figures of debt whether you pursue the field of pharmacy or not. Have you considered working as a contractor pharmacist for the military or straight up apply for the services? How about US Public Health Service? You could also work as a GS federal worker with its benefits as well. The only hard issue I cannot understand is why you would have to pull out an additional $100,000 for just one more year of schooling. If your grades are outstanding, consider taking your absence and talk with a military recruiter OR work as an intern in another location (I am not sure if your intern license is still active if you are temporary on leave with no academic discipline). The services will pay 120k of your debt for an exchange of 3 years plus housing benefits and you get great work experience when you leave.
If your anxiety and stress is a bit higher than it should be, get a referral for a behavioral health specialist. You'd be surprised how much that could help you in organizing the secondary opportunities you may still have should you not pursue your schooling.
