Persephone
You know....when I am in the place that you are in right now, I usually find that I am on the verge of a lot of things falling into place. There is some truth to the night being darkest before the dawn.
You may be in a place where you need to "make amends" as they say in 12 step. Maybe the amends will need to be made to real people, maybe to yourself. It may seem as though that is a mere symbolic gesture--but whether it is or not, it really does work. There can be tremendous psychic freedom in doing it.
Do you journal? I find that journalling, especially the free-writing described in The Artists Way, is very helpful in sorting out all the jumbled painful thoughts like you are having now. Just write and write and write (20 minutes at a time) and let all of it come out without editing. Dont lift your pen from the page. Dont even go back and read it--the act of writing will bring to the surface the things you need to address. You could even write your way through the first few 12 steps to give you a focus...but maybe only after a few days of true free writing.
Your friend who was critical of your writing was really in a different position than those of us here. When you are writing something for publication, it is not the same exercise as when you are unburdening yourself to friends, or when you are journalling. There are other things that become paramount--you are writing for the reader now, not for your own understanding. Sometimes it takes outside people to help you judge if you have accomplished that. Sometimes you are not ready yet, to have those tender feelings and struggles put out there for publication. You can take what this woman says and let it help you decide if you are ready for what is to come: significant critique of your writing.
It seems to me that there are two things happening simultaneously in your life: One, you are wading through a lot of your pain, trying to make sense of where it has landed you. Two, you are writing--for publication--about the wounds that created that pain. The writing of it, and the anticipation of publication, may be bringing up a lot of stuff that is causing you to be self destructive. I think it would be very, very valuable to journal what may be happening. I think that the free-writing exercise would help you examine it more closely.
Publication should be at the time-table that is best for you. I think that you have some very valuable things to say to the world that will shed a lot of understanding on the subject of narcissism. But the world can wait until you are ready to handle everything that comes with publication: your mother's reaction, criticism from both publishers and your readers, the probability that you will have to explain yourself over and over. Publication will be a significant event in your personal life. It is tempting to think that publishing will be the final chapter in your journey through your wounds, but in many ways it will be much, much closer to the middle chapter. It will be the part of the story where the hero steps into the dark woods, uncertain of what she will find there.
Much good luck to you in this venture, Persephone. I hope you will stop for a moment to give yourself a chance to take a breath and let all the jumbled emotions that you are feeling settle out and let you look at them.
