I had a bad reaction to anxiety medication, which threw me into panic attacks. I had a head change since then that has not changed at all. I feel very mentally vulnerable. Depersonalization, disassociation, change in vision, vertigo, unable to have a constant sleep pattern, minor hallucinations. Nobody can figure out what is wrong with me, the only medicine that has provided any type of relief is ativan and it does not always work %100. I am so paranoid about something being wrong with me, like cancer or some other serious illness.
