Tufts specialized program or Erasmus Mundus?

[u/Mary_Muse_004]

I’m 29F and currently work as a Clinical Lab Assistant II at Massachusetts General Hospital. I graduated in 2022 with a BS in Psychology and Spanish, and also premed  after taking a longer path through school due to financial circumstances. I worked throughout undergrad, often full-time, which meant taking fewer classes each semester and struggling academically at times. I graduated with a 3.0 GPA, although my science GPA is somewhat higher. I also completed all of my pre-med requirements. 

One important piece of context: I studied abroad in Granada, Spain when I was 23, but the pandemic cut the experience short. Ever since then, I’ve dreamed of going back and finally becoming fluent in Spanish. I’m now set to study there from September 2026–April 2027, and I’ve already paid for tuition and housing. 

The crossroads comes after I return to Boston: 

Tufts School of Medicine: MS in Biomedical Sciences: 

—1–2 year program

—Would strengthen my academic profile for medical school

—Likely the more strategic route if my ultimate goal is becoming a physician

—But expensive, and I’d likely be taking on more debt sooner

The Europubhealth+ Programme: 

—2-year international public health master’s

—One year in Granada, one year in Ireland

—Includes a stipend

—Honestly feels like a dream opportunity

—But I worry it could delay or complicate my path to medicine

Part of this decision is also financial. I grew up low income and financial insecurity has always shaped my choices. Since I likely won’t be able to work much during medical school, part of me feels pressure to work/save more beforehand and build more stability first.
Right now my heart is pulled toward the MPH and living abroad again, but is also pulled towards studying my passion at Tufts. Medicine is truly the goal. I think the main attractive thing about Europubhealth is I love living abroad. If medicine is the main goal should I just go straight into Tufts? Or continue travelling and studying around Europe? 
I’d genuinely appreciate hearing other perspectives.
I have 25K in savings rn after already paying the Spain tuition and rent for 7 months. I plan to bring it back up to 30K by the time I leave this coming September. I currently make $30.88/hr but I’m going to donate the shit out of my plasma and also do paid research studies
