Years ago I found myself in your situation, I put most of it in a big box and sold in on craigslist and started over because organizing it all just demoralized me. Bought a bunch of resistor and capacitor kits from mouser or digikey that came with in their own storage, small parts cabinets of drawers. The drawers are all larger than needed and come with dividers so I was able to consolidate a few and have some cabinets for the parts I kept and ICs. The electronics distributors all sell these cabinets as well.
