There is a [discussion](https://english.stackexchange.com/questions/101029/is-it-appropriate-to-add-a-postscript-to-an-email/454198#454198) of the use of postscripts in email messages on [English Language & Usage](https://english.stackexchange.com/). The discussion was closed as being primarily opinion based, but one thing to consider is that a postscript can be used as a deliberate style choice rather than _just_ adding something at the end because you are unable to edit what you had written before. For example, adding something brief and very much off topic at the end of a message in which the notation itself would not be appropriate. One of the answers in that discussion is my own. I won't quote it here, but I'm somebody who has always used postscripts stylistically—never in the "too difficult to edit" context in which they originated. I will make specific mention, however (as I did there), of Karen Hertzberg's blog post ["What PS Means and How to Use It Correctly in Your Email"](https://www.grammarly.com/blog/what-does-ps-mean/). It expands on the idea of using postscripts stylistically. But all of that aside, you can literally do whatever you want when writing your own diary entries.
