Your daughter is having drug addiction
And she developed factitious dermatitis
and nodular prurigo due to disturbed mental condition.
Immediately she should be taken to deaddiction center nearby in your city.
The doctors in the center would thoroughly examine her, take complete history and do blood investigations.
And they will start the treatment for deaddiction..and they might refer to psychiatrist
Anxiolytic and antipsychotic drugs might improve her psychological status.
Local steroid cream and oral antihistaminics would improve.
If the skin condition is severe, oral steroid would be used.
I think, she might be improved.
