Quarter of the way done and still clueless!

*Downer Moment Alert*
I was tallying up my internship hours today and realized I have already passed the 300 hour mark, so I am a quarter of the way done with the hours requirement. That is so crazy that is is going so quickly. I can't say that I am remotely feeling secure in the position yet though. I honestly still feel like I am clueless. Shouldn't I have got a bit more of a handle on this by now? I thought I was starting to figure out one of my supervisors report writing styles, but then (after emailing it out to everyone and making all the copies) I discovered that I had screwed up and left out an entire test from the report. Ooops. So I asked if I should just re-do it quickly and add in the missing stuff and I wasn't given the opportunity which frustrated me beyond belief! Today I floundered my way through trying to explain to a kid who really liked working with me that we were done testing. He was so sad, which was completely endearing, but just another thing that I need to work on. There are just SO many things to learn and to see! I can't seem to keep track of it. And at times it is really tough to keep up with having two supervisors at 3-4 schools. I can't remember which one wants it which way at which site! Can you tell I'm kinda whiny today? Sorry about that. I will try and chipper back up before next week.
