This tiny book isn’t going to help you in a way a medical professional can. This book can help, but it is nothing compared to what a person who knows what they’re talking about can do for you.
Go to a doctor.
It can be the doctor you go to for random aches, nasal abnormalities, or thyroid medicine. It can be a fancier doctor that went to school for a long time specifically to help people with our problems.
Hell, it can even be a therapist that doesn’t have a doctoral degree at all.
Just, please, go to a doctor and tell them something is wrong.
