I can really hear the hurt and distress in your post. It sounds like it's coming from a very young place. Can you hear what a lot of people here said, they are saying that you can feel your feelings but don't have to act on them. From reading your posts here for a long time, it appears you feel all of these emotions, get overwhelmed and act on them very quickly. Can you sit with them for a while chew in them and let them digest?
Your t was being real and sometimes reality hurts. Nobody can say what will happen in the future but right now she is here for you! I think your t is trying to prepare you for the inevitable- when she isn't there. How would it be to support yourself right now, by being kind and giving yourself what you need to soothe these horrible feelings?
There is support here, perhaps venting to is instead of your t might help?
