Dear Sherlock,

I took that job at the hospital, so now I'm working on Mondays, Tuesdays, Wednesdays and Sundays, 9:00am until 6:00pm, and I do night shifts on Fridays. I started on Monday and I'll tell you now that it was one of the best decisions I could have made. Just to feel useful again is a joy, and helping people has always been a priority for me. After being left without you to help, Sherlock, the hospital is a factor much welcomed into my life.

I remember you telling me that caring about people won't help them, but, as a doctor and not a detective, I can't help but care for the people who I treat. If you don't care about them then you can't really help them, as you'd just ignore how they're feeling and that wouldn't help them get better. But I understand why you did not deign to care for the people involved in any of your cases.

You had several people who you did care about, though. Mrs Hudson, Greg, me, and maybe even Molly, to some extent. And I know that even though you class Mycroft as your arch-enemy, don't try to tell me that you didn't care about him too.

And these are the people you left mourning you, Sherlock. And we are still grieving and some of us are still not able to believe that you're dead. You were far too clever, far too strong to ever have killed yourself. Or so we thought. It's just so difficult to comprehend, and so painful to think about.

I'll write again soon. In a week, like always.

Your John.
