High systolic bp and breathlessness

[NoaS]

Hi i am a 17 year old who works out 6 times a week, lives a healthy life, doesnt smoke,drink or do ANY drugs. Im gonna keep this as short as possible with as much data. This problem started in march of 2022 where my systolic bp was really high and i had shortness of breath and mild chest pains. What happend then isnt really important but a month and a half goes by and i was hospitalized for some test to see what could have caused the hypertension. After 5 days in the hospital they didnt had any conclusion really as the test ALL came back clean and they sent me home. So after that i got a little bit better but i still to this day i still have these symptoms but are mild in compare as how i had them in the first place. Shortness of breath, heart palpitations, high systolic bp and mild chest pains are all the symptoms i had and still have from time to time. I am usually a tough minded person and never had depression or anxiety until recently it started to take a toll on me mentally. Ive started to have anxiety from that day in march. Now as im writing this i checked my bp and its 135/60. For the first 3 months my mental health was good like i said i never had any mental problems but now anxiety is hitting me and thats why i am fed up with this, doctors arent telling me anything and on 30th of august i am having a check up appointment and i will ask them for further tests. I was googling a little (i know googling isnt the best thing to do when it comes to stuff like this) but i read about pulmonary hypertension and i have similar symptoms to that. I will ask my questions on the appointment but i also want to hear from any of people reading this if they have any idea as to what this is or have some suggestions as to what i can do. Have a good day!
