I'm sorry to hear about how you are feeling. I think it's pretty common to feel that way from what I've read. Symptoms can come and go. My son had what they called a mild concussion 8 weeks ago playing soccer but it's been not a mild experience at all. My son has been suffering with severe headaches ever since. It seemed like they got worse as time went on. He had a CAT scan that was normal. He is a healthy young boy with no issues otherwise. Our specialist says every concussion is different and where you get hit affects how you feel. He was hit in the back of his head so he is more dizzy and has the headaches, but no cognitive issues. Our specialist says it can take a very long time to heal fully, even up to 5 or 6 months. I just keep hoping my son will wake up and feel good one morning. Rest is the biggest thing my son does right now. I wish you the best and hope you feel better soon! You take care.
