Thank you for getting back to me. Your turtle doesn't have symptoms of any common diseases, but from your description, she is near death. We'll do what we can. Don't soak in carrot juice. There's nothing in it that will help. Instead, buy some Pedialyte (yes, the kind for human infants). Prepare a shallow bath consisting of 1/2 water and 1/2 Pedialyte. Soak your turtle for about 20 to 30 minutes twice a day. Reptiles can absorb the electrolytes and fluids through their vents (where droppings pass out), so make the water deep enough to cover the vent. Be sure to supervise closely.
Some of her symptoms sound like she is suffering from Metabolic Bone Disease (MBD). It's too bad she won't eat the cuttlebone. Your UVB light is fresh enough, so that isn't the problem. A calcium deficiency may be responsible.
I also suspect this turtle may have been born with a genetic condition of some sort, since the problem has been going on so long. This is called failure to thrive, and little can be done about it.
I wish I could give you a home remedy, but this is a situation where there isn't one. The Pedialyte soaks will help with dehydration. Beyond that, all you can do is make sure she is warm enough. Your water temp is good. The basking area should be 85*F to 90*F in the daytime.
If your budget allows it, I recommend a visit to a reptile vet. These sites have directories:
In the meantime, check your temperatures and provide Pedialyte soaks. This is a very difficult situation. The soft shell and shrun***** *****mbs are very bad signs. I'm sorry not to have better news, but I believe you deserve honesty. If you have more questions, let me know in a REPLY.
