Brain malnourishment causes bizarre thinking and is a fundamental obstacle to recovery. When your brain does not get adequate nourishment your perceptions are distorted. You can't make sound and reasonable judgments. You can't take on realistic responsibility for your own responsible self care.
In the video, created as part of Joseph Campo's work in infant research at UC Berkeley you'll see a baby negotiating something similar to your situation. He knows where he is safe. His perceptions tell him where danger exists. He won't go there. But with encouragement from a trusted and loving figure he will ignore his fears and move through what he considered dangerous to get to a worth while prize. For him, the prize is a toy. For you, the prize is your life.
