If you wish to write about something in your past then you always have the right to. However, please make sure to take into consideration how your story will affect not only you but your wife if you give out the details. For instance, if your wife is a politician and you did something while in a depressed state which could cost her an election then talk with her first. The problem with posting on the web is that stories have a way of coming back to you and loved ones when you least expect it. If your writing is a way to gain some catharsis then you may wish to write a journal, or write a fictional story based on your situation. If you want to write your story as is, then maybe you can create an account without listing your real name in the profile and slightly change certain details like the place where incidents occurred.
