Hello, I'm 18 years old and a female, I've been having abit problem with my sight when I woke up from sleep or after laying down, sometimes I couldn't see, it was pitch black and I lost my balance, it lasted for a few seconds about 30 seconds. I often to have a headache too but I've a mental breakdown few weeks ago and whenever i cry I've a really bad headache. Could you please help me to find if I need a further treatment? Thank you.
