i have no idea what to pursue in life

hello! for context, i'm 19f, in a very happy relationship, and i currently don't have any university / college education.

i'm just really so stuck and lost in what to do, how to move forward, and where. i want to do everything right so that my future self doesn't suffer the consequences of not only my lack of action but the wrong course(s) of action. in high school i was an honor roll student, i was in mental health clubs and leaderships, and every summer including this summer, i worked at an elementary school helping kids with their literacy.

my plan out of high school was to take a break and figure out what i really wanted to do. i had plans of being a psychologist, but i'm genuinely too brain fogged and put bluntly i'm really stupid. i have no motivation for anything and suffer immensely from anxiety in regards to school.

ever since my bf and i started dating, i've figured out one thing: that i ABSOLUTELY want to marry him and settle down with him. we have plans to move to another country, have children. realistically, while my bf is saving lives, i'd stay home to take care of our children which i have no problem with but to me, that also sounds like putting a career i might've worked so hard for on hold.

i really want to be an elementary school teacher but i'm in a financially tight spot so i had also been researching dental receptionist positions since they make max $50 per hour, more than i'd get paid working as a public school teacher. it's not only a shorter and inexpensive course that'll gain me quick experience, but it'll make me arguably more money. on the other hand, i want to be successful, i want to have a career and change lives, but with how everything has been money wise, my desires feel very limited. i don't want to drown in debt. i just want to feel happy with what i've done with my life.

any advice/guidance/anecdotes are so appreciated thank you
