Are we talking about a return of your natal mercury or mercury being direct?
They are two different things...
If you are talking about a natal return you need to have your chart looked at and compared to the current chart of the moment.
That said, returns are processes of being aligned to ones own vintage in some way and could indicate going back to ones core or root self in some way. The best thing to do is take stock of your life and ask yourself if it is really aligned to who you are. If it is not, you can use your natal return to get that aspect of your life back to what suits you. So, if things aren't working for you, working with Mercury at this time will help you understand and apply your native mercury ....
If you are experiencing issues and they are because of Mercury, it is likely that your intellectual and communicative pursuits are in conflict with your needs concerning intellectual and communicative expression.... your native Mercurian traits coming through strongly with nowhere to be channeled thus becoming disruptive.
