Cleaning up my hard drive...
Get an external drive and move the library to it. Even if you make space now, presumably you will still be taking photos and so will fill up the space again. Even if you are really strict at managing new images.
You only have 10% of your boot drive free and that is scary. You are close to the time when you get data loss, and funny file things happening.
