Why is my sister experiencing anxiety attacks without any reason?

Name: Kabira Date of Birth: 4th May 1997 Place of Birth: Pune Time of Birth: 6:55 AM

My sister has been experiencing anxiety attacks more frequently in the recent past. Constantly she simply cries and states that her chest is tight, her heart races too much. We have even brought her to the physicians and all appears to be okay spiritually rather than physically. As she brings whatever she can before her feet, I am powerless to rescue her. I just started to wonder whether this has something to do with her birth chart - as it may be that her Moon or Rahu are not working. Will you, can you see whether her planetary movements are the causes of these anxiety spells?
