History of weed smoking. Activities a!

Hello Doc, Got introduced to marijuana by a friend when i was 16. I smoked, chewed and drank it with tea. About a week later i got so high that it took me days to come back to myself. Couple of days later went high again without smoking. I've read online that weed gets out of your system after a couple of weeks but i developed BP problems and have been battling it ever since.its been 13 years now and i still feel the effect. my BP is usually between 130/140. i used to take blood pressure medications but stopped 2 years ago. When walking i cant feel stable,I dont mean i cant walk, i do walk well but i don't feel my mind really focused, i feel slightly unstable(don't know if i'm putting it the right way). I haven't smoked even cigarette ever since ie 13 years and i rarely consume alcohol, but still feeling the effects of those few weeks. I did medical exams, met a cardiologist and my results are normal. I feel tense most of the time and cant really focus. I do my daily activities a
