Symptoms Hypertension

I’m 22 years old and I am in between jobs so this has all been unprovoked, I am under no stress. It all began last month i felt signs of my mood being down then one day it hit, I started having severe trembling panic attacks that felt like heart attacks that would last up to 10 hours every night, my symptoms were trembling, hypertension(uncontrollable and overwhelming energy in the pit of my stomach), nausea, fear, depression, depersonalization/derealization (felt like i was dreaming or going crazy, to the point i’d question if i was in a dream) memories didn’t even feel real they felt like dreams also, suddenly became suicidal which for me is wierd i have always been the brightest most easy going guy i know. These attacks lasted for about 2 weeks then when they stopped i had a severe case of GAD, small things like thinking about my condition would cause my pupils to dilate, I’d then become extremely sensitive to sound and light and my mind would race to the point where i wanted to scream it was uncontrollable. It then went on effexor and stopped 4 days into taking it because my symptoms were worse when i was on it, I’ve been off all medication for 12 days now and feel I’m mentally getting better my current symptoms are constant headaches, blurred vision, severe acne which Ive never had I’m 22 and this is the first I’ve experienced acne, Nausea, and sores on my legs and in my mouth, occasional anxiety mixed with DP and DR but not half as bad as it used to be. If anyone can please tell me what happened to me or what this is i would greatly appreciate it, like i said I’m only 22 and i feel i’m getting better but am wondering about things like diabetes which my doctor refuses to test me for and beyond that what could have caused these other horrific symptoms? My doctor is very young and can’t give me any answers.
