I don't think it crazy at all, to write to them! It is theraputic! And it is very sweet and brought tears to my eyes! The missing them never goes away, but it does get easier,, I put my 16 year old cat down a year ago in June, and all I have to do it think about her,, and I will bawl! I feel your pain.
