Welcome to nursing school! lol. Like someone else mentioned, there WILL be those, such as myself, who are jealous of your situation.
And yes, it's been an emotional roller coaster. My first Med Math exam I BOOOOOOOOOMBED. Ended up 0.5 points shy of an "A". I can do DA in my SLEEP. WOOHOO! As for semester two- Med-Surg has already made me cry twice. (Like you, I have no previous medical experience.)
However, I am an organized FOOL. I bought the little colored tabs that Post It makes (I think Avery makes them now too) and I label the pages in my binder according to subject. For instance, for Med-Surg I have a label for Electrolytes and one for Resp. As we go on, I'll add them for other subjects. I do the same thing for Patho and Pharm. (We're lucky in that each class is timed with the others so we're covering the same systems at the same time. LOVE that!) As for the handouts, I have one of those small three hole punches in each of my binders so I can immediately punch it and put it in my binder. Handouts that need to be turned in go into a folder.
Also, I put the same labels into my textbooks so I am easily able to find each system. (This cuts down on the amount of time it takes to flip to the correct page. Sounds silly, but it cuts down on my annoyance level, so it ends up being a huge deal to me. LOL!!!)
Good luck! Remember to stop and breathe when you start to feel overwhelmed.
