Maybe you can just be "exploring all the facets of your personality" , or something equally New Agey. I don't know how old you are or where you live, but young people today appear much less rigid in their self definition. I'd say be happy with a fluid existence, until you find a comfortable spot to settle. I'd leave any forums that are unfriendly, and let the members know why.
As for medical advances, by definition we don't know what is around the corner. It will be interesting to see.
