Getting sucked in

I know that one of the hardest parts of nursing is not getting sucked in to the sad stories and drama of our patients, but in home health it is so much more difficult because you are right there, amidst the drama.
I have had to really stand back and harden my heart, and that makes me sad. I can't believe how many people are living alone, need money, need a phone, need money for meds, need their med fix, need AA, NA, need SOMEONE who cares. And we are the ones who come in for a job and are the only ones in their lives who do care. But it is a job, and you can't get sucked into enabling. For me this has been one of the greatest hh challenges.
The patient who calls me because I live a mile away, she is SOBBING because her caregiver has called in sick and she is laying in feces, and will be from Friday until Monday.
The patient who is drinking a beer at 10 am but "has been up since 2 am so it's really like 4pm right now" and three days later you see her in obvious withdrawl, needs an ativan and no one will prescribe because she is a drug seeker.
Yes, on everyone I call MSW, the psych nurse, but it is always the case manager who's shoulders it falls on.
I am exhausted. I really like the simple wound care cases. The drama gets to me.
