Hi Selkie:
I've struggled with this, too: If I'm OK, will I have anything to say? And the answer is an unequivocal YES! For many years, I wrote in an effort to explain what I was feeling. Writing was my primary method of compensating myself for what was missing in my life. And then things got to the point where I even denied myself that outlet; I didn't write at all for about ten years. I thought that part of my life was over. I entered therapy for what I thought were other, more pressing reasons, but I know now that what I really wanted out of the process was to get my creative self back.
And it happened. I started writing again, and have continued. Though I still use my past as a source of material and inspiration, it doesn't control my creativity. In other words, I'm not writing entirely as a reaction to the past. I can honestly say that I have moved on to what interests and moves me, not what I feel I have to "get out" in order to stay afloat.
I think you may be going through a transition in why and how you create, but please don't stop thinking of yourself as a creative person. Perhaps your job in all this is to keep the juices flowing, even if it feels forced--do exercises, visit museums, read books that are far from your "usual" choices. Keep yourself open to inspiration, and I'm pretty sure it will come.
For me, when art seems to be far away, I enjoy craft. Generally, I cook, since I can't really do anything else very well. There's tremendous satisfaction in making something good, and it occupies your mind wholly. Sometimes that's a tremendously freeing experience; you just don't have the mental space to worry about anything else. And in that calm interlude, sometimes an idea can take root. I've started many poems over the stove.
I know this post probably sounds more optimistic than you feel at the moment. I'm only trying to offer my experience, because it seems relevant. It has been okay for me, and I believe that if you leave yourself open, it will do the same for you.
best,
daylily
