First,I want you to know that I am an expert on all of the symptoms you are experiencing. But, I think you're in the wrong place. Are you currently under stress of any kind? Sometimes we can be under stress and not even know it. Somthing can cause us stress even if we don't think it is. Has anyone mentioned Anxiety to you? Even if you have never had anxiety in the past various things can cause it to develop. Every symptom you described sounds like Anxiety, could even be deprerssion. Heavy head, dizziness, pressure rapid heart beat, tired, can't concentrate. Take my advice and before you freak yourself out, go ahead and ask your doctor about anxiety. I get all of the symptoms you are describing and then some. Try the boards here on Anxiety-actually I think it's mental health here. You'll find that alot of people with anxiety describe exactly what you describe. What happens with anxiety is it totally exhausts you to the point where you feel tired all of the time and the reason a person with anxiety has this feeling of pressure and heaviness in their head is because anxiety is a form of stress although some of us may say,"I am not stressed" stress isn't always on the surface. One more thing to consider, depression is also a leading cause of these symptoms. Look up on this stuff, it will make a world of difference. It sounds like you may have had a panic attack if you woke up with a rapid heartbeat and sweating. I bet that was scary wasn't it? I know exactly how it felt. It happens to me quite often. I hope this helps. If you have any questionson this don't hesitate to ask.
