To Sister, This Heartfelt Sonnet of Love

Dear sister...You, Charles, and Mom: all three, a part of my life forever; I love you all! But this sonnet is writ for thee (and for thee only): for you are, above all, my sibling Achates—bosom friend in my life and help in my poverty and suffering. You are my childhood's Godsend. I know not the veiled reasons or the why of my hard, joyless life; but, that nevermore could I remain your role model, the one you copied and looked up to like before, because mental illness left me undone. So, because of your steadfast love for me, heaven's a place—I know—reserved for thee.
