do you ever feel overwhelmed with responsibility?

I have a TON of blood draws every week. I have to watch my fax machine and know when to call docs and when to just fax the copy to them. I have to keep up with who needs a port-a-cath flush on what date, when a f/c needs changed, etc. On top of it all, patients call me and want me to call their md for more pain meds, or call me over some silly thing. sometimes I just feel so tired of trying to keep up with everyone. And then the patients will call me over something that Im not even there for. One wanted me to contact her insurance company to set up an ambulance ride to her MD appt. Does anyone else ever feel overwhelmed?
