I know we can suffer from depression with psychosis, but was is your perception of how it feels?

I sometimes wonder if I suffer from psychosis, or if it is depression with extreme anxiety.

From what I gather, psychosis does not have to include hallucinations (Visual or hearing voices). I definitely don't have that.

My depression just lands up so deep (NOT SUICIDAL) but painful. An open hole in my heart. I feel such chronic loneliness. And this is where I keep having people tell me it is not true. That they are there for me, and they do care. But I can't shake this feeling.
Would that still classify as psychosis? I know at the time, or a short while thereafter, that those thoughts are unreasonable, but it doesn't help my feelings in the moment. No, I cannot talk myself out of it!
