Studying, training, I don't know what to do?

Hello everyone,
this time a more existential question.
I am 18 and this year I started studying medicine at a university far from my hometown, which is why I moved away.
Since then, I've had an extremely difficult time and it just doesn't get better, no matter how hard I persevere, no matter how much I involve those around me.

I never wanted to leave my hometown, and I never wanted to choose a degree program like that. I graduated from high school with a perfect grade, but I never had any desire to become a doctor or anything like that (unlike my classmates, apparently).
During and after high school, I couldn't actively address the question of my future because I was paralyzed and afraid of making the "wrong decision." Everyone wanted an answer to the question, "So, what are you going to do after high school?" Even though I didn't even have the answer myself.

Because I excelled in every subject at school, I didn't have any clear interests or talents. What I do know, however, is that I have to invest a lot of time and effort into science subjects, whereas things like languages ​​or the humanities simply come naturally to me.

I am now very desperate: on the one hand, everyone is telling me what a unique opportunity this is, that if they were in my position they would have killed for it, but on the other hand, I am also making it clear how incredibly bad I feel (sleep and eating disorders, panic attacks).

After graduating from high school, I realized how much I needed home, my friends, and family around me to be happy and feel safe. I'm not someone who needs to travel far away, but I can still live independently.
I'm convinced I can still develop further without pursuing this career path and moving far away. Especially since healthcare isn't the most attractive field, even though you can earn a lot as a doctor. However, you'd need a practice for that, because nobody wants to work in a hospital voluntarily. At least I don't.

I am considering doing an apprenticeship or a dual study program in my home country, like my friends are doing and like my family has done.
I won't look back after graduation and say, "Oh great, now I'm a doctor. I struggled through a tedious and lengthy training program and, on top of that, didn't see my family and friends for 90% of the time for 10-12 years (study + residency). It was worth it."
It may be a secure job, but I want to find meaning in it for myself. A good salary, a secure job, those are nice things that make life easier, but what good is that if you're unhappy?

I realize there's no such thing as a dream job. And you'll never achieve perfect happiness. You always want what you don't have.

I would be happy to elaborate on my case further if there is interest.
My question to you would be:

Do you regret your studies? Should you have listened to yourself or others?
Are you happy with what you're doing? Where do you see yourself in 40 years?
All these questions… Just as I did, I invite you to "vomit out" your thoughts on everything.
And please don't answer with "Ultimately, you have to decide for yourself." I know. But I'm not going to turn to others for that.
