Wow, you sound a lot like me. I have the same struggles with phone conversations, relationships, taking notes, etc. My mother was a lot like your mother, constantly telling me I was worthless, stupid, selfish, etc.

Have you tried bringing a small tape recorder to your anatomy class? You'll at least be able to replay the lecture later. If you replay it over and over something will sink in eventually. I bought a digital sound recorder to record meetings at work. It records lectures and meetings really well. It comes with a USB cable so you can upload your recordings in mp3 format on your computer so you don't have to worry about buying tapes. If you're like me you will probably lose your tapes so I definitely recommend digital.

I've actually thought about nursing school too. I was also toying with the idea of becoming an EMT. Are there any EMTs here?

Good luck and keep us updated.
