I think I'm starting to understand what happened. I would recommend that you go easy for a while, giver her some space and time to process things. And yes, that means not leaving any messages.
I would recommend the same to you in fact.
I believe you both had different perspectives on your relationship and interaction. To her you're probably a great friend that she enjoys spending time with and filing the role of a motherly figure, nothing too serious, meaningful yet just fun. But I think to you it became more than that. It became serious, it seems to me that you became a little obsessed with the relationship and what you were getting out of it that it distorted your view of what it really is, just two adults enjoying the company of each other, and although you can forge a deep bond with someone and have something truly meaningful and great, there's the risk of going too far, and I think you did a little bit.
However, I believe there's a really good chance that she will continue to be your mommy and spend time with you, but for that you need to give her some space and time, go easy with it and respect the fact that she sees your relationship differently.
You'll know when it's time to contact her again. When it starts to get better again and the pain of not being with her starts to fade, that is when you should contact her again, but go easy.
