(BPD comorbid with Paranoid PD)

It’s impossible to tell whether my paranoia about certain things is justified or whether I’m being completely irrational and just don’t realise it. How am I supposed to trust the “evidence” and “facts” in my head when they might be twisted by my mental illness? I can’t trust anyone 100% but I also can’t trust myself when I know I have these disorders. I don’t know how to tell when someone is being honest, or how to tell something is true. Doubting everything that comes out of anyone’s mouth but also feeling like my own thoughts are lies too is like living in a world that isn’t even real. 

I fucking hate this.
