I cannot see my bookmarks and discussions when I click on them. This is what I see
I don't know about the bookmarks (having never used that feature), but I think the empty "My Discussions" page may be because the "My Discussions" list only shows activity in the Categories section. It doesn't show anything that you've posted to a Group.
If you go to your profile and choose "Discussions" there, it'll show every thread you've started.
(Note the absence of the possessive pronoun on the label. "My Discussions" is a different page than "Discussions".)1
Thank you for your time and help0
