@Faceplant8: I feel your pain. :P

Probably only one way out of this, if you have no way of constructing even a raft: Destroy your bed and get yourself killed by a deathsquito. At least it will be quick. :P

You will wake up in the circle of the Forsaken sacrificial stones and hopefully get to one of your bases from there.

Edit: Can you at least build a portal in your "lean-to", so you can come back later with the materials for a Karve or something?
No-portal run, I forgot.
