Yes, Jax is right. You are a wonderful friend just as you are and I'm sure she appreciates you. That she asked you to walk and be with her in the first place is wonderful. I have a work friend who has "random" panic attacks and the only thing she can do when one starts is go home from work and take her meds and a nap. I think your friend was brave and was surprised she was able to stay as long as she did!
