Realizing the berries might be poisonous, you keep walking. Deep down, all hope is lost. You accept it. You're going to die. Our here. Alone.
Clearly, you're lost. Your arm throbs and hangs, useless. With all your might, hang on a low branch, pull yourself up, crawl toward the trunk, and climb to the safety of another branch high above the ground.
You fall asleep, hugging the trunk, and never wake up.
