I posted a question before with my symptoms and now I have some new ones. In addition to having headaches every day, memory problems, dizziness, and lightheadedness, I am having trouble remembering words. They make sense in my head, but when I say them, I'm using the wrong word...like the other day, I meant to say "idiot" but I said "indian" or I saw my sister's smoke detector hanging down from the ceiling and I said, "Hey, your flame alarm is broken." Earlier in the day, I had gone to Dunkin donuts and ordered and paid for my coffee, then walked out to the car before I realized I hadn't actually gotten the coffee! I'm only 26 years old, I don't do drugs or drink, and have never had these problems before. I'm not stressed or depressed (which is what my doc blamed it on). WHAT IS WRONG WITH ME????
