Told my mom about the past

Tonight we had a discussion that was worthwhile. She hasn't been very supportive at all. Tonight she asked me:

Mom: How long have you had the hallucinations?
Me: I started having visual hallucinations at age six. Auditory at age of ten.
Mom: Why didn't you tell me about it?
Me:Because you would throw me into a hospital.
Mom: I wouldn't do that.
Me: Yes you would, I decided to keep my mouth shut about it all these years.
Mom: But why?
Me: Because you wouldn't understand. You wouldn't understand one bit.
Mom: Let me try, try to understand.
Me: I don't know.

I started having hallucinations around 9/10. I told both my parents this, they said I must be imagining things or have false memories because they don't remember it. I KNOW they don't.

When I told them about it, they didn't listen to me. Until I got 13 and I was put into a hospital and put on Zoloft, but only for depression. I was too scared to say I hear extremely scary/weird things all the time to the doctor. I know i'm not imagining things. I have drawings dated back to when I was 12/13 of stuff I saw/heard. So it's not lies on my part, but rather denial on theirs.

This is why, by now, I do not talk about that stuff, only to my dad. He is supportive enough because he at least listens. I mostly don't talk about them though. As well as, my feelings, because it's all connected. If I have to answer why I am sad, forget it, I'll just say "i'm fine", because it'll be the vicious cycle of, "you have false memories". !!!
