Nostr.band is really good for search (except I wish nostr:npub1xdtducdnjerex88gkg2qk2atsdlqsyxqaag4h05jmcpyspqt30wscmntxy would Nick off that fuckin Nostrin bot which spams results).

Use the advanced search for date ranges which he implemented after I requested. Search your npub and a word you would have used in the post and you should be able to find what you’re looking for. I regularly use it to reference my old notes but I have exceptional recall which helps a lot.
