Potentially serious health scare at my follow-up, not sure how to react.

Been on T since December 5th, low dose ,2 ml injections weekly. I went in to Planned Parenthood and had my blood pressure taken this morning.
Except the lady had to take my blood pressure 3 times with two different devices becuase she was so confused as to why the first was so high. So she took two more. I really don't know how to read for blood pressure estimates or gauges but the numbers that were detected on each test were 160, 170, and then 180.
She asked me if i have a family history of Hypertension, i said i wasn't sure and that was basically it and there was no further mention of it. And from what the internet told me i should be on deaths' door with that last number. So now I'm confused as to what to do or think, if it was THAT high wouldn't they try to get me to go to the ER?!
i've had no vision issues, headaches, or weird pain. The worst I'm dealing with right now is hot flashes (I think becuase i went slightly lighter on my last dose,)

I'm ashamed to admit i am not doing good to help on my end either, and idk if its my T that's worsening it. I've been off work for 2 months since its seasonal, so I'm not out on my feet all day atm, still trying to squeeze in cardio with this freezing weather a few times a week (not fun). Mental health and recent events that i will not mention these last few months has kinda drawn me to substance abuse (alcohol and weed) that i have repeated a few days in a row prior to this follow up (though back to back days of heavy drinking has occurred in the last few months). I didn't drink the night before becuase i have been working on cutting back on this bad habit, and the mental benefits of T are helping to encourage me to do so.
I cant be out about this to family becuase they are unsupportive of trans rights and are Conservative, even though i am 25 years old (cant afford to move out), i have little privacy, and my mother is very nosy of my whereabouts, i could never come up with a good argument for an ER visit without them finding out I'm taking T.
I'm just hoping this is a fluke, becuase I'm really trying to better myself.
