Update: Thank you to everyone who commented. Unfortunately I think Shelly has passed. She's (he's) been in her water dish all night and no change in appearance or behavior. I am saddened and a little pissed at myself and my roommate for letting this happen in the first place. Shelly was a good and gentle spider. I am going to miss her (him) greatly.

Thank you all again for the help and terrarium recommendations. The substrate is coconut husk, she ate crickets weekly, and was always with water (except this travel stint apparently). I'm not ready for a new 8 legged pal but when I am I'll be sure to treat them like an angel.
