I am not my thoughts?

From some research I have done, it all points to we are not all of our thoughts. How does this work out when you talk and respond to voices? My thoughts are bad right now, and I'm trying to make sense how I'm supposed to go about not believing or buying into them when I feel that some of the thoughts are actually mine. I feel utterly crazy and awful and I have no one to talk to about this.

I'm also sorry if this post doesn't make sense. I am having a difficult time articulating my thoughts right now.

Thank you in advance.
