If writing is life to you, then you have a right to identify as a writer.
New Year's Declaration: I am a writer. I know this because I need to write, I am not ok when I can't write, or am otherwise prevented from writing. It doesn't matter whether anyone else likes my writing, but I do want to share it in case someone might like my stories. Likewise I don't care whether anyone says I can't call myself a writer if I haven't yet achieved official publication status or monetary compensation for my writing. Visual artists can call themselves artists because they create art, regardless of whether they have achieved a status of supporting themselves at it professionally. I believe in the same for writers. If you write and really care about your writing, then you are a writer if you want to be and believe you are, if writing is a part of you, in your soul.
New Year's Resolution: I resolve to no longer apologize to anyone for doing what I have to do in order to be able to keep writing, and commit to writing. If I don't keep in touch with people as much as they want, if I don't take care of my health as much as people think I should, if there is any other thing that I have to do or not do in order to keep writing, that is for me to decide, and no one else. It doesn't matter if people don't understand why I do the things I do; if it helps me to keep writing, then it is necessary for me, even at the expense of other things. I will not accept guilt based on anyone else wishing I were different. I have to be who I am.
Besides, there's not much else I can reasonably do anymore anyway. I have to write.
Writing is Life.
