Hello Matt0419: I'm sorry you're experiencing this difficulty. The Skeezyks' perspective would be that there really isn't much you can do beyond just being generally reassuring. This person needs professional help, which is presumably why she's been accepted into this clinic. You mentioned helping her learn. I suppose you & / or your sister could spend some time with her watching some mental health videos, on YouTube, related to her areas of concern. PsychCentral has a YouTube channel where you might find some applicable videos. Another source would be California therapist Kati Morton who has her own YouTube channel where she uploads videos on a wide variety of mental health topics. This might be instructive. Just a thought...
