Hello, i?m 17 years old and i?m a female. I?ve read online that sleep deprivation affects my memory and iq. I?ve been feeling and seeing signs of memory loss, trouble concentrating, and i?m mixing up my letters a lot. I haven?t been sleeping well for the past few years and I really need help because I think my mental health is not how it used to be. If I go back to a normal schedule sleeping schedule, can I go back to my normal mental performance? Please help me because i?m feeling terrified for my future if I continue this route. I keep feeling ?dumb? and I can?t learn in class properly, please help me.
