How much have you had a chance to talk to her about all this? She really has her work cut out for her if she wants to make it so everyone is comfortable. I think that requesting that of her is completely okay. If she loves you and cares about you then she will do as you ask and attempt to negotiate better boundaries.
You seem to be asking for daily emails, some loving words, and attention to your needs for closeness when you can't have that physically. Am I right? Is there more that you need? I would request that those needs be met in order for you to feel loved and explain to her exactly what you need to here and how much. Maybe she is just unaware of what your love language is.
Perhaps this link will be helpful.... sharing it with her even more so.
