Help! Sling, Molting or Dying?

[The Spider Prince]

I've had my H. coecatus or H. pyrrithrix sling for about a month now. He is wild caught, found missing his back-most left leg and with an injured front-most left leg. He stopped eating last week but has been on a steady every-other-day diet of fruit flies and/or mealworm guts. Last night he was sitting in the same spot I found him this morning. I know slings will sometimes molt outside their hammocks even if they have one, which he does (a few actually). and he is responding when I lightly blow on him. When he reacts to this stimulus it seems like his joints are locked up. The thing that concerns me most is his position - he looks to be in a death curl, but he is still alive. Is this a sign of a mismolt?

Looks dehydrated, if still alive I would place its mouth over a droplet of water

I think I was just a bit too late. I didn't consider dehydration because I mist his enclosure every day.
He doesn't seem to be responding anymore, even after getting him some water droplets. I know I shouldn't be too disappointed, because I know slings often die even when you do everything right, but I'm still sad that my little Sevens didn't make it.
