I couldn't find any other place to post this type of question. Is there any way that I can search my previous posts?
You could go to your profile page and browse through them.
You don't have that many, so it shouldn't take long.

It has been asked and answered many times in the Website and Forum section.

As for actually searching (rather than browsing) your posts, the only way is to do a standard forum search (via the magnifying glass icon on the top bar of the website) and to add your user name to the search query. Since your user name is not a common word, this should work well enough.
