You basically described my family too. My brother claims I'm making everything up, he's in the military and says mental illness doesn't exist. But he says PTSD does. Total hypocrite. Anyways. My sister says something is obviously wrong, and I'm completely different off and on meds. On meds for the better so I guess she agrees with me. I grew up as a Christian Scientist. We didn't believe in modern medicine, and definetley not metal health issues. So growing up alot of my symptoms could of been managed had my parents sought medical intervention. Anyways. I know exactly where you are coming from when it comes to family members not believing you. My grandmother says it's animal magnetism that I need to practice. I really think she's off her rocker but that's a totally different story. Wish you the best of luck!
