Cathy, you might benefit from watching this (warning: long) video about the diver's ear. There's a lot of good information there.
Many people come out of OW class unsure of how best to clear their ears. Pre-pressurizing before descent can be useful, and it's also important to clear very frequently while descending, because past a certain point, it can be difficult to impossible to force air into the middle ear. New divers get so task loaded on descent, with managing their BC and monitoring their depth, and forget to equalize.
Feeling creepy in very low viz is a pretty normal occurrence. It gets better with time and experience, and having a good light can help a lot.
