I have episodes of passing out, i sometimes cant breath in scary situations other people would call normal (example: driving over a bridge) im in tears by the time were finally off of it and usually cannot catch my breath. ?

Medical assessment : You need a full medical assessment. The fact that you are hyperventilating to the point of passing out is very DANGEROUS when you are driving. Medical cause need to be ruled out. Any medical causes should be treated. In the meantime , strongly recommend some form of psychotherapy. Psychotropic medications may be indicated as well.
