Dearest Robin,
 Im so sorry ...

Its really hard to know what to write at this time.
I can truthfully tell you I feel what your feeling and I wish I could show you more than words alone. A hug sent by mail is hardly enough but I hope you recieve my thoughts for you at this time. 
You are a truely wonderfull human who has made a great deal of moments in my life better due to your words and our friendship. Also other people I know who you talk to have always showed bothing but love for you as a person . Im so sorry Ive missed so much and am never around to underdstand whats going on.I would always reply to my mail and if you ever want a chat please just call.

I will email you soon.
I dont want to stop writting but this isnt the place.
I'll be watching my mail if you want to talk,
My deepest sympathy and love.
Calum
