Hi. I'm due to start immunotherapy next week ,the thought of having medication going in me is so absolutely frightening, I get so anxious having any sort of injection,I'm having Ipilimumab and Nivolumba ,I'm reading nivolumab may need 1 going through a tube in my chest is this correct? I don't know what to do I can't bare the thought of it all.. I suffer mental health anxiety/ depression, please help
