I don't like the idea of a medication to blunt your senses, seems like it would be similar to the self-medication route of alchohol and illicit drugs. You can't live life numb.
Giving yourself some time alone, your faith, seeking counselling or professional help, sabbaticals and road trips, quilting, gardening or any number of other things that help you get through are all healthier, and better for a long-term outcome.
Part of being alive is the rawness of the whole thing...love, loss, laughter and tears...we have to accept it all as part of the deal.
