I get what you’re saying; I get mini panic attacks every so often when I worry about how I’m doing as a premed student. But I think you should take a deep breath, because you’re only a freshman. Focus on finishing out the semester strong, then use the summer to shadow in the fields you’re interested in; ask your dad to hook you up with some doctors if he works in a hospital.
And if you are actually interested in it and like it, and want to do it for reasons other than wanting to please your father or out of the fear of not having a job, then in the fall, make an appointment with the health sciences advising committee. If they’re anything like the pre-professional office at my school, they can go over how the application process works, and help you plan your schedule so you’ll be able to fit all the prereqs in. Then for me, I just check in every once in a while to make sure that I’m on the right path GPA-wise and not forgetting anything extracurricular-wise. They answer any questions I have (about summer courses, how to find shadowing experiences, etc.).
But don’t start planning until you actually know what you’d be getting yourself into. You’re already ahead of the game science-wise, at least.
And as for a website, most premed “Everything You Need to Know” guides make me antsy because it’s too much info, and they’re often very big and specific checklists (be interesting- check, get 300 hours of volunteering- check). For me, it’s better to have the broad overview and research on my own the specific things that I want to know more about. I found this on Google; and it has memes

And if you actually end up needing it, a pro-tip that’s not as abrasive and sounds easier to do than, “Find something that makes you stand out, and be amazing at it, but don’t do it to check boxes; be passionate,” because you might start hearing this once you descend into premed land: http://premedrevolution.com/premed-to-a-t-the-most-interesting-applicant-in-the-world/
Also,
Maybe this is what you should be looking into to ease your anxieties, since this is what you want to do. Med school plans can wait until your heart is 100% in it.
