It's difficult to give other than a very general, and therefore not very helpful, answer, without a chart. So of you really want to explore the issue, post your natal details (not a link to chart). Both Dave and I will find it easier to create the chart and include our own preferred information, especially as creating the chart in software allows manipulation, such as looking at current transits.
I've known people with Mercury (and other planets) retrograde who function better during the retrograde periods. Also, Mercury is not just communication, so if retrogradation is the issue, then Mercury's other roles in your life should be affected.
If you choose to take this further include:
Date of birth in the format day, month, year, eg 10 July 1980
Time of birth - show whether the time is am or pm or use 24 hour clock
Place of birth.
BTW, if you think I'm being a bit pedantic with dates and times format it's to prevent me making an error. The US uses a different format than most of the rest of the world 7/11/1991 means July 11th in the USA and 7th November elsewhere.
I also have a bad habit of missing the am or pm info, much as I try to avoid it. That can give a chart 12 hours out. So I prefer the 24 hour notation to always get it right.
