I've been diagnosed with anxiety and ADHD. I'm not taking any medication.
So lately (for about a month) I've been feeling sort of light headed, tired, and feel like part of my mind is somewhere else. At first I thought it was just tiredness, but I took a nap and it was the same. I seem to be able to zone out easier than ever (which isn't all bad, since I feel calm when I zone out and I don't have any thoughts running through my head) but it's staring to worry me. I've also been confusing some of my real-life memories with my past dreams, but I'm able to figure them out in a few minutes.
This is hopefully just ADD, and I'm going back on meds soon
