Honestly, I think it's best that you move on from her and to a new T that hopefully treats you really well and responds during emergencies, etc. Especially if she didn't reply to you when you were sui or having an emergency...you need someone that can help you through these times, not just ignore you. This isn't your fault at all. If I had a T that ignored me in my time of need (and I've had Ts like that), I'd get rid of them straight away. So perhaps it's best for you that you're not seeing her anymore.
