Just how untrustworthy/unreliable can your thoughts get when you're severely depressed?

I'm wavering between thinking I see the world as it really is and understanding that depression can really screw with your perspective. I just feel so muddled up about what is real (if you can even confirm that). I'm just so tired of not knowing. Feels like I'm torturing myself with the back and forth and the hopelessness.

For background, I've been depressed for a long long time and made my first suicide attempt as a teenager so I feel like maybe I've grown up with distorted patterns that hang around even when times are better.

I thought that my partner was abusive and tried to escape in the middle of a snowy night with our dog. That was depression x.

Depression can definately squew our thinking, it can also lead to psychosis in some people. What kind of things are you talking about?
