I'm upset and need help please!!

Ok so I'm on my very first period right now at age 13 and every morning so far (4 days) I have been nauseous and throwing up until around 1:00 pm. Day 5 is coming and its getting lighter, but after the period is over does ANYONE know if I'll feel like my "normal" self after until the next ones? I know I'm crazy I just want to know if I'll ever get to feel normal and how long until 😭 please please help me!!
