Switch back to the old version and see if you recover those then.
To switch back: hover over your name and click on settings. In the next screen scroll down till the bottom and tick the box where the red arrow is, and click on save.
Then you might have a chance to see your personal comments again.
If you afterwards decide not to stay on the old version, tick the box one line higher, click on save and you're again on the new version. Good luck.
