Is it that difficult to change your major? You are in in your first year. You may have wasted a year of school but you know physics does not make you happy.
I noticed the second thing you mentioned was writing. Writing may or may not pay a lot but I suggest you continue. Most writers don’t write for money. They write because it makes them happy.
I watch many videos that are not at a desk/studio and wonder why some YTers e aren’t using more mics.
