Hi there ~
I understand your concerns. I am sorry to hear about the problem with your kidneys. Once you have been having problems with overdosage with medications especially opioids, kidney damage may be normal. I also believe that you will do well with consulting a psychiatrist who is experienced in drug abuse
problems so as to get the appropriate treatment. Other organs may also be involved and you should consult a psychiatrist
to make sure that you get a complete check up to make sure that your other organs are healthy.
I hope this helps. Take care and have a lovely day!
