I can't see anything or go anywhere. At first, I thought I was in the void, but I realised I wasn't falling.
I was sitting in a cart and I suddenly realised that the height around me was too small, so I started to lose health from suffocation. Suddenly my PC turned off; when I turned it on again, I was stuck and couldn't do anything. My health bar was full too. How can I kill myself to respawn? Or, better yet, is there a way to get me unstuck?
