Like what The_Evil_Immortal said your personal issues and problems are more important than focusing on your readers. As long as we know you will update it's fine

That's fine, take your time writing. I think as long as you update people will be happy even if it's a late update. It's very good

This is really good with very minor grammatical errors. I very much love Cain's appearance and that he's paired with Alice and not an OC. Probably one of my favourite Twilight stories
