Why is my RAM being used so much?

Your RAM is there to hold processes when they are running. As RAM is a volatile memory used to hold instructions and data of currently running programs, once that program is closed the memory will be flushed out. You may experience high RAM usage due to overcrowding of a ton of internal processes. In order to fix it, your best is to close all the redundant programs.
