I filled my bath with hot water and relaxed for a good thirty minutes, I then stood up and stepped out of the bath, my sight went spotty green then black still aware of my surrounding I felt my body shake intensely but I could not do anything els for a whole minute, why is this? It also happens when sitting in my chair and standing up but never this intense, had I not stepped out the run Im certain I would've drowned. Also aftereffects included a intense pending of my heart. Is there a diagnosis for this? Or even a treatment? Please answer soon I'm 14 and scared for my life
