I can totally understand. I have been a nurse for 5 years. I work med/surg, tele, stepdown. I have seen a lot of the same issues and drama's. Had one the other night. I kept saying to my self why bother.
Remeber this: You will make a difference to someone almost every day. You may not see the effects or be told. Your patience, understanding, caring touch will matter to someone. It might not be a patient but a family memeber or a teenager in the hallway who you didnt know was watching.
Sometimes I have to remember the lil things to get by.
