I am so sorry to hear Laura's had a slight set back. Kudos to you for not wanting to put her on Paxil. Achieving her goal will help alleviate her stress. Have you talked to her about how she's feel having you at her therapy? If not, maybe you should. Just ask her, point blank, if she'd be more comfortable and less stressed with or without you there. How she feels is the most important thing.
Hang in there, and prayers are still going up. Friday is not too far in the whole scheme of things, really.
