How do I view my past posts?

Have you been inactive for a while? Current internal search seems to only go back a few weeks or, at best, about three months. It's an ongoing issue and the Mods are aware of it.

The workaround I use is a site-delimited web search. For you, this search string should work with any search engine:

"jjjefff" site:discussions.apple.com

• For a username like yours you can omit the quotes, but they are required for names with a space like mine.
• Also note: NO space following the colon after "site"

should be under subscriptions.
