12 Hbwr Seeds And Vasoconstriction?

Hello everyone, I am new to this forum and would like to know if this trip I had 2 days ago was serious? It's also going to be a mini trip report, but if you don't have the time to read it, skip the next paragraph.

This was my first psychedelic (besides cannabis) and I scraped off the outer layer of 12 HBWR seeds (Hawaiian Baby Woodrose). I chewed them for about 15 minutes, then each minute after that I swallowed only a little bit (to reduce the impact on nausea a little bit). I drunk some orange and mango juice about 5 minutes after swallowing all the seeds, hearing that Vitamin C can intensify many psychedelics. The taste of the seeds reminds me of the smell of coffee beans to be honest. Anyway, I had pretty strong warping, melting, breathing etc. visuals and big objects looking tiny. In the trip I was reading that vasoconstriction can lead to gangrene and I started panicking. I vomited 3 times and I was on the floor wondering if I would get gangrene and was extremely scared about dying or even getting any of my limbs cut off. I saw that my skin was rotting away (I thought the sores I already had was from that vasoconstriction. But I honestly think my skin did go pale because of the vasoconstriction.) I told my nan to take me to hospital and she dropped me at my mums. My mum took me to hospital and a nurse wrapped a thing around my upper arm (I don't know what it is called) and she said that my blood pressure was very high. A cool thing about when I was panicking, the world went about twice as fast, the internet went extremely fast and the drive to my mum's was as well.

My question is, would the vasoconstriction from 15 HBWR seeds and less be considered "dangerous" and risk anyone (without any blood/heart problems) getting gangrene? Or could the vasoconstriction lead to permanent physical health problems? I also would like to add, that I am pretty sure I vomited blood. Thanks.
