Hi! According to my doctor, dysautonomia can cause disassociation given to the bad circulation of blood which can no go properly into the brain and also affect our heart rates. I was actually diagnosed with dysautonomia when I was almost 17 after going through a harsh period of disassociation in which I felt completely unattached from my loved ones and my reality. I also felt I was about to faint and my hands would get extremely cold. I hope you are now doing well, keeping hydrated, adding more salt in your foods and not drinking much alcohol, at least that’s what has helped me. I think it’s important to remember that everything you’re going through is valid and will eventually pass. Sending lots of love and support to this community
