No need to share your email or private info here. I think what @supernovia is asking if if you can tell us if there have been any other changes to your site recently or any other odd behavior that has taken place as well in the last few weeks. Have you added any new plugins about the time you saw this change? Is Google Analytics something you have connected only recently?
One thing to be aware of is that Google Analytics uses different methods to identify and track activity on your site compared to what Jetpack uses. With this in mind, it is normal for the stats to always show slightly different totals for your visits, views, etc. However, you should see similar trends and patterns in both stats packages.
