question: My sister had a tumor removed from her lung and developed crepitus when the lung did not seal around the chest tube.  It was a severe case and resulted in emergency surgery to repair the air leak.  She was on major drugs for 15 days and is now showing signs of severe depression, not eating, afraid to go to sleep, etc.  Could these be drug withdrawal side effects or could something else be going on?  She was very close to dieing when they did the 2nd surgery and is now afraid she is going to.  Is there something we(her family) should do to help her through this?  Thanks
