Game was great, until it glitched and I lost everything!

I was chilling on the left ish island, putting some items in a chest, and it crashed! Now my back pack is basic, and everything I have done is reset! I can still fast travel to where Ive been, and I have my notes, but my ammo, my guns, everything else is reset! Please fix it, I dont want to have to replay my stuff back!
