Daughters freezing ever since attempted suicide, why is this?

My 13 yr old has been home with me now for 18 days. Ever since she's been home she's freezing, her hands & feet are ice cubes, and shes wearing jeans & jackets in our almost summer weather.

Could this be related to her attempted suicide? They were not able to get a body temp on her for 2 days while she was in the ICU. Could her body just be trying to get back to normal? & if so how long does that take?

If it helps, she took 2 bottles of blood pressure pills & let's just say we are very lucky she's still here. **She's getting treatment for the suicide matters, I am just asking about the body temp/freezing matter**

No rude comments, please. & thank you in advance for your help.
