I'm 25 Years Old With A Past Of The Bath

I'm 25 years old with a past of the bath salts for 2/2.5 years, been clean for 3.5 years, female. Every so often I get so light headed that I feel like I'm going to pass out, and I have around 10 times. I'm pretty sure I was 15/16 the first time I actually passed all the way out, falling and not positive what had happened when I come back to. I couldn't tell you how long I stay passed out.
I had that feeling today during work just standing in line, getting food. When I feel the feeling I know I have to sit down, and quick. Well I took my blood pressure on a machine they have and it came back 155/93 and my heart rate 106..
I'm not on any medication and I know that's not around the normal BP or heart rate. I just need to be informed, I'm scared, I'm 25 in a couple weeks, I hate doctor offices, hospitals, so please if you could tell me what this means or what I need to do, no idea... please help
