Exhausted after masturbation and dizine.

Hello there I have been facing problem with fuzzy vision and eye floaters. More over feeling exhausted whole day and dizziness.Sometimes mood swings.I used to spend much time in front of PC and notebook systems as unable to stare at white backgrnds and thick red backgrnds and moverover sunlight,vehicle head lights became my enemy. I used to masturbate /EJACULATE 3 times per day but I have reduced to 3 times a week.Few days back my BP readings showed 155/105, 160/103, 140/96.I have used amlodopine 5, avacard-AT but there is no improvement in dizziness and exhaustion.Certain tests like CT brain and 2D echo showed normal. RBS showed 145, fasting sugar 90. And climate heat tolerance is low. Summer is like nightmare to me.At some instances felt like suffocation.Sometimes I get shock kind of thing in middle of head. These shocks,dizziness and eye floaters are very annoying. Some physicians told as per BP readings I am hypertensive. But hypertension  can't be there for 365 days.Please suggest
