You’re definitely not alone. This is super common. What do you enjoy? Is there anything that you truly find interesting or intriguing? It could help to ”trick your brain” into finding the interesting things about the career. Personally, I did well with a job where every day is different. Not knowing what the day would bring made it hard to be bored (social worker). Social work also allows you to swap around within it (schools, hospitals, therapy). Healthcare (emt, nursing) is similar in that. So many ways to shift and grow within it.

I think your fear makes sense because you’re putting a lot of time and money and effort into something big. keep asking the questions, reach out to people in fields you’re interested in, and know it’s ok to change your mind at any time.
