Recently, I have been becoming more paranoid. I do not have BPD or psychotic depression. Lately, my intrusive thoughts (thanks to OCD and decreased mood) of turned into proper paranoia.

I am not sleeping well at night because I lay there in near complete terror. Looking towards my door, laying against the wall. My partner has been trying to help me get even some sleep, but when I do sleep I am so anxious before it that all I have is nightmares. And I wake up hyperventilating.

Is paranoia in severe depression or (what I have) major depressive disorder something that sometimes happens? I know I have been more stressed than normal. I am living between my parents home, and my apartment with my partner. My father had open heart surgery and then was in a coma, and life changed yet again. I am wondering if anyone else has gone through this?
