Hi there ~
I understand your concerns. I believe that your sister need immediate medical attention for a probable gastritis
at the very least and a perforated gastric or duodenal ulcer
which needs immediate surgical attention. Her inability to breathe is also attributable to her using bath salts. I also believe that she has been using meth for a year now and that it has affected her lungs and other bodily systems as well. She may be a fit candidate for psychiatric rehabilitation
and a consultation with a psychiatrist
who is well versed
with substance use disorders will be able to help. I hope you have her visit with one as soon as possible.
I hope this helps. Take care and have a lovely day!
