Hi,
You will first evaluation for cause of blood pressure. You should undergo test like kidney function test, 
renal artery doppler, Sr cortisol and 24 hr Urinary Metanephrines. Also get 
lipid profile and sugars tested. I think you should be started on tablets like 
Prazosin or 
Clonidine which are highly effective in controlling BP. 
So request your doctor for these and to reduce dose other medicine like 
Atenolol and other. Also have healthy lifestyle like avoiding fatty, oily and high calorie diet. Have low salt diet and monitor blood pressure regularly thrice a day for one week then once or twice a week. Regular exercises like brisk walking, jogging according your capacity at least 30 min a day and 5 days a week. 
Eat lots of green leafy vegetables, fruits, fish once or twice a week, and avoid meat. Avoid smoking and alcohol if any. There shouldn't be abdominal fat deposition or obesity.
Hope I have answered your query. Let me know if I can assist you further.
Regards, 
Dr. Sagar Makode
