Hello laazrook: I see this is your first post here on PC. So... welcome to PsychCentral! I hope you find PC to be of benefit.

I'm not a mental health professional. So I can't offer you anything definitive with regard to what you're experiencing. But, from what you wrote, it sounds to me as though you've sunk into depression. So I would presume your thoughts & memories are all still there. You're just having a difficult time accessing them, which is something depression does to a person in my experience. Perhaps being here on PC can be of some help with that. You may also want to consider seeking some mental health therapy if you're not already involved with it.

Here are links to 2 articles by our host Dr. John Grohol, Psy.D, from PsychCentral's archives, on the subject of depression:

Introduction to Depression

Living with Depression: A Guide for Coping with Depressive Feelings

Good luck...
