Health anxiety…keep checking my blood pressure and it’s ruining my life

So…I’m looking for some advice. I was out on adhd medication just over a year ago now. They told me I need to check my blood pressure often because it’s a stimulant so blood pressure and heart rate will go up. I have now gotten to the point where I am thinking about my blood pressure and heart rate every single second of the day. If I don’t check it I panic. If I check it and it’s high I panic. Even when the reading is healthy…I panic. My highest readings are 125/85 which is only borderline and I know that’s okay. Please can anyone help me because it’s ruining my life.
