As others also suggested, you don’t have to decide anything now. But based on what you said, it does seem to me like you would want to start in a first-year engineering program and see how that went. That doesn’t mean ruling out going to med school, but at the moment you don’t really seem all that enthusiastic about that path.
Speaking of which, I note there are many, many ways to be a health professional of some sort without going to medical school. Engineering is one such possibility, but there are also a variety of other licensed professionals, business types, government/policy types, scientists, and on and on.
Again, you don’t have to decide yet, but I think being aware there are so many other paths should help reduce any concerns you have about starting along the curriculum path that seems to make the most sense for you.
