Good nurses are in short supply. It's been a while since we talked, but in my own re-entry to education, I've felt some similar stuff and for my part, I wasn't able to hold it all together until graduation. But, I'm feeling better after a break. Not the point!
What I will say is, I had a meeting with my advisor where I was talking about my chosen discipline (conflict resolution) and parallels to music. You are a musician. What I was saying is that I feel like sometimes in dicey situations, I have to fall back on lessons that I learned from music; I know the changes, the progressions, my own capabilities, etc. and a lot of it is dealing with the emergent as it comes. And as you know, in live music playing with other people, that means fucking up and then bending it around so that it isn't so much a fuck up.
If you know your shit in nursing like you know your shit in music, are these fuckups things that will totally derail the flow? I have no idea, but you probably do. It might be hell right now, but if qualified experts said that you were cool to drop in, maybe there's something to that. On the other hand, given that you know yourself, are there things that need to happen so that you can take care of yourself and thereby be better situated to help your patients?
Anyway, I hope that things work out man. Send sweet jams when you can.
