When things get confusing

Lucy and Liam have been friends for longer then either of them can remember but they never anticipated this to happen. Neither Lucy nor Liam can understand what is going on in their heads, it has never been easy with them, there had always been problems but never as big as this one, the problem is Lucy still doesn't know what it is. Liam is too scared to tell her the truth worried that the fact of the non-excistant cure could be the reason for her to walk away from him, but he doesn't seem to realise just how life defining it could be. 3 words and she would know the truth about him but is he ready for her to know?
