Doctors get paid to hear people rattle about stuff. I don't personally believe that any person is a waste of a doctor's time, for anything at all. Everyone is worth it. My doctor has always stressed that if you have suicidal thoughts then you should see them immediately - after all, the point of medication is to improve your symptoms.

Sometimes it gets better after a couple weeks, but even so you should still let them know what's up. Please do get in contact with them, even over the phone might they speak with you?
