I'm scared I got diagnosed with hypertension/high blood pressure! Doctor said it was hereditary?

So I went to the doctor yesterday cause I felt a little uneasy, so I went and told him about my current health stuff, did a checkup and found out I had hypertension because my numbers read 140/100. So should I be scared? Or will I be fine with meds alone? I am a male 23 years old. Please answer.
