Hi Mrs Xxx ! Thank you for posting your questions here. I would say that according to your blood pressure and the symptoms you have this should be something that you have to start medication and to do further evaluation to find out the main cause if it s one . In this condition we say you have high blood pressure stage 2 Feeling lethargic ,anxious or irritability are some of the symptoms of high blood pressure . Unfortunately the medications against high blood pressure need a local doctor prescription .You should try to have a doctor appointment , since you have been diagnosed with high blood pressure he /she may prescribe Enalapril 5mg x day and other dosage or drugs until your blood pressure gets back to normal .The doctor will check your heart(ECG , ) , kidneys , cholesterol level and hormonal examination . According to the result he may also add other medication to descreae the blood pressure. Meanwhile you are waiting for the doctor ,follow these advise: -Don t do exercise when your blood is high - try to relax -Reduce salt and calcium , fatt intake from the food , no smoking no alcohol ( if you do) Eat food that contain magnesium and kalium.
