Two nights ago I went through my regular routine and jumped in bed to go to sleep. After closing my eyes and taking a deep breath I jumped up and was afraid my heart stopped beating. It didn't. Everytime after that I tried to fall asleep I would jump up and be all freaked out about nothing. My heart was pounding and I just felt like something was wrong although nothing was wrong physically. It was just a scared feeling. That has never happened before. And ever since then there seems to be a haze over my grasp on reality and my vision is jittery. It feels like I am high on drugs but the only medicine I take is Allegra for allergies and this never happened before. Also, I feel slight pressure in my head. It is pretty scary and it worsens when I am tired or sitting still for long periods of time. If I am busy I don't really notice it. Everything is normal (appetite, bowel movements, conversational skills, motor skills, thought processes) I just feel cloudy like I have a fever or something similar. My blood pressure and heart rate are normal. What could it be? I am afraid there may be something wrong with my brain. I have done my fair share of recreational drugs, but not for months and months. Could it be linked to that? I also had an ear infection about a month ago, but that got cleared up. Could it be a relapse? Any advice would help. I think I'm going to the doctor on Monday to make sure I'm okay.
