Dear Icey, It's almost impossible to say without the chart, without knowing the elements involved, the planets, the house. In general, the person is experiencing enormous changes in their life which are rocking them to their core & taking away any sense of control & security they felt.
They feel completely abandoned & don't know who to trust or where to turn next. They will get some answers & some help with the supporting Jupiter - Mars transit but they are on the brink of great changes which they are not sure they can handle. Great loss, great despair, great pain.
Are there any major aspects with their Mercury? The transits will last for a couple of years & there could be more supportive ones coming up, that's why it's imperative to see the chart. Overall, the person will change radically their beliefs & who they can believe in anymore.... women involved in a consequential way, maternal energy very afflicted also.
