It may be that you are over treating your hypertension. Also some of these symptoms could be hormonal related.
Hello,
I am so sorry you are experiencing this. It sounds to me like a form of an anxiety attack. It can also be due to low blood sugar, are you eating enough? Are you drinking enough water?
If this continues, I think I would see a doctor, he/she can help with prescribing anti-anxiety drugs if you are having anxiety attacks.
