So, your public inbox and outbox relay list only has relays that are not available anymore. Basically only primal's relay is working. That's probably why Amethyst couldn't load much. If you load your npub on Amethyst and open the relay page, you will see that all of the download and upload stats show Zero (nothing is being downloaded or uploaded). You might want to delete and add other ones like nostr.mom and nos.lol. Primal has a caching server. So I think most of your posts are loading only from their central server.
