USPS lost my Package

I’m devastated that this happened to me. I bought a really expensive Hermes rep and the seller sent it via USPS. They marked package as delivered but when I went to the mailbox, used the key to open it and the mailbox was empty.

I am devastated. No insurance and absolutely no way to get anything back and seller is not being supportive. And I had even mentioned to the seller when they said they ship USPS that I don’t trust them and they insisted that “FedEx is at a higher risk of being seized by customs”.

I even did a police report but I’m afraid I’m definitely screwed out of my money.

I cannot express how sad and disappointed and heartbroken I am. It’s the first time I invested so much money in a bag. I can’t believe how much frustration and desperation I’m feeling. Has anyone else experienced this?
