How does work-life balance look like as a paramedic

Hi! I'm considering going into paramedicine/emergency medical services. I've always been drawn to medical fields, but honestly, I don't have the patience to study for another 12 years to be a doctor (university, internships, specialization).

However, I have a few doubts about the paramedic path, specifically regarding private life.

Long working hours personally wouldn't bother me too much, but how do you find someone to build a stable, long-term relationship with? I'm particularly worried that I'll simply end up alone for the rest of my life. What about starting a family?

And what does it look like in old age? I've never heard of or seen an older female paramedic (though that might be because I'm young).

I'm also stressed by the fact that after just a dozen or so years (around 30!) people in this profession burn out and have to change their job field (which I would prefer to avoid at that age). I have very good (and boring) prospects in a completely different field (economics), but I can't combine the two paths. I"m in my final year in hs.

A bit of context from Poland. Our healthcare system here is really overburdened. I've already read stories of people working 300+ hours per month. Plus, our system is public/free, which combined with a severe shortage of medical staff makes conditions quite harsh. I couldn't post this on the Poland subreddit because it won't let me (it's been months lol and I still can't), but I guess asking about private life is probably similar in each country.
