I don't know if its available for sure, but many crisis centers like that have a counselor available for staff/volunteers. Is there a way that you could talk to them? I'm sorry that you are feeling so triggered - is it possible to text T back and let her know that you understand what she's saying but thats not what you need in this exact moment and perhaps ask her to help you find a more immediate way to cope and then consider the cause later? I'm so so sorry you are struggling. *hugs*
