Sounds a lot like its all in you're head. You saw the symptoms on YouTube and suddenly you went from perfectly fine to having those exact same symptoms. Let me guess..the more you think about your symptoms the worse they get? If you were going to have a seizure it would of happened already, no one has stroke like symptoms for over a week. Plus your symptoms are jumping around, first one leg, then another, then a foot, now your forehead. Real symptoms and conditions rarely jump around like that. The fact that you admit to having health anxiety before should give you some comfort because you know how HA can be. Stop thinking about it and keep yourself busy with something that will keep your full attention. You'll see that the entire time you're staying busy you wont feel anything in your legs but as soon as you begin to worry about it the feeling will come back.
