Have you drawn comics about your home? Or written about it and done some illustrations? That will preserve your memories, and maybe you can sell the stories of your past life as fiction later. @Shezep has written about their past life, so they could give you some advice.I have fears similar to this, bit instead for me (because of a past life I have experienced) it is that I am losing my true self. That I'm falling too deep into the act and this life, that I'll forget what my home looks like or that no one will remember me when (if) I ever come home.
