My (F44) best friend (F39)has had breakdowns and spirals consistently about every 4-6 weeks. I have been able to text her through a hard time validate her thoughts and feelings. 

But the last 2 weeks they have been back to back and it is draining. I have to make sure that I can sit down and text her and mentally and emotionally prepare myself.

I don't really have a problem with her emotions as she is going through it, but they are very illogical for the situation. I am a very blunt person but I know enough to bite my tongue. I don't know what to do in situations where she wants validation but is lashing out unfairly at her stepkids (F19), (M17) and (M15). It is pretty common for her to do that, but when she would calm down, I could point it out and she would be able to see it and apologize. Besides being nonstop now, I am having a hard time biting my tongue when she wants validation and support from me.

Am I enabling her? What can I do to help her?
