Firstly, congratulations on writing your memoir 😊 I think it's marvellous.
I don't have advice about publishing, but a relative who has had a very interesting life wrote a memoir and it was clear from the feedback that she got, that it needed editing, which is a skill not everyone has.
I read a book on the craft of writing and what struck me as good advice is that it's a good idea to share the final draft of the book with a few trusted readers, friends, relatives, "opening the door a crack", before "throwing the door open wide" (publishing).
