I'm here. I'm ready. You haven't come back. I need you, but you're not here. I'm coming to find you, Sherlock. Wherever the hell it is you went.
I'm here. I'm standing right where you stood. I'll follow you. I'll always follow you. You aren't coming back and I can't take it. I'm sorry.
I'm here.
I can see this being either Mycroft or John on top of St. Bart's. Or both, really. The first person and lack of any other character leaves it open to interpretation. In any case, this is my first Sherlock fanfic. Please don't kill me for any feels you may get.
