Hi Sarah, I'd like to help you with your question.
It sounds like your friend may need to find a new therapist. Often, finding a therapist you can work with is like finding a family doctor. You need to see a few before you can find one that works for you. Your friend can ask her doctor for a referral or if she attends church, her pastor can help. She can also look on line at http://www.findatherapist.com/.
I assume your friend has been diagnosed. From what you described of her symptoms, it sounds like she may have a depressive disorder and an anxiety disorder. It sounds as if outpatient therapy and medications should be helping her. Sometimes, different medications need to be tried before one will work. If what she is on now is not helping, she should try another medication.
It sounds like you are doing a lot to help your friend. Being there to support her is one of the most important things you can do to help. Taking her to appointments helps too. She probably appreciates someone going with her to help her hear instructions and to talk with her about her treatment. Also, when you talk with your friend, she needs reassurance. Anxiety causes a person to feel nothing is safe and that they are in danger most of the time. Reassurance that she is ok and nothing is going to hurt her can go a long way to help her refocus.
There are some books you can get for her as well. One is called The Anxiety & Phobia Workbook (New Harbinger Self-Help Workbook) by Edmund J. Bourne. Another is The Mindfulness and Acceptance Workbook for Anxiety: A Guide to Breaking Free from Anxiety, Phobias, and Worry Using Acceptance and Commitment Therapy by John P. Forsyth and Georg H. Eifert. For her depression, she can try The Mindful Way through Depression: Freeing Yourself from Chronic Unhappiness by XXXXX XXXXX, XXXXX Teasdale, Zindel Segal, and Jon Kabat-Zinn. For you, here is a book to help- The Real Friend's Guide To Depression by Mr. XXXXX XXXXX. You can find these on Amazon.com or your local library may have them available.
I hope this has helped you,
