Did you mean 6 months, because I would expect issues to come up much sooner than 6 years in those conditions.

Temp needs to come up to the 80* range, but do so over the course of a week.
Humidity should also be near 80%. Get digital gauges.
Use spring water or treated tap water, the distilled will leach nutrients from your frog.
The point sticking out on her right side concerns me greatly, could be a bone sticking through which could easily perforate the intestine.
The not eating for that long after a large mouse at that low of temp isn't surprising.
Again, bring up the temps and hope for the best. If it isn't acting like it's in pain you may be in the clear. If the frog is in pain or acting very sick/lethargic, get it to a vet immediately.
