You may find it beneficial to spend some time 'tuning out'.  There are plenty of recordings of relaxation music available which may help you in your quiet moments, and some could even be used as background music in appropriate parts of a service.

The good thing about this sort of music, is that often you have not heard a particular piece before so it does not invoke any previous memories or specific thoughts - so these are great if you are after a neutral piece for a particular reason.

I hope that you enjoyed the samples above. 

Although some of these samples are unable to be purchased through Amazon, please still take a look to see what you can find.  There are a number of relaxing instrumental pieces (often interspersed with the sound of water and/or nature) available to purchase and sample....
get comfortable as you could be there awhile!
