Hi thanks from your question.
Relax there is nothing to worry.The pain, bleeding,dizziness
and turning pale all could be due to fingering.During fingering you had injured her vagina or cervix
,most probably cervix as bleeding was more than expected.This gived her pain and bleeding.Dizziness and turning pale could be due vasovagal reaction resulting from stimulation of external oss (portion of cervix) by fingering.Loss of hearing is not relatesd in any way to this sexual act ,could be hysterical.
Hope this answers your question.
