I am 28 years old. I have problems with my memory in a sense that someone will talk straight to my face and I don t realize they have said anything. I constantly have to keep notes or I will forget what I needed to do. I am very tired no matter how much I sleep. I m having trouble copying numbers or other things correctly at work. I feel foggy in my head. I do not have headaches however I feel very moody or grumpy lately. I am taking Vitamin D as I had a deficiency. I do not take any kind of medications and I am not a drug user. I had an MRI done and my scan was normal however this is really affecting my life. I need help.
