On my first North-South transcontinental tour (Canada to Key West), the first 15 days were non-stop torrential downpours. I seriously considered quitting but stuck it out. Once I abandoned all hope of being dry, it got a lot better. At night I'd camp in commercial campgrounds, take all my stuff (which was soaking wet) to the camp laundry and dry t in the big dryers-- it helped being able to put on dry clothing and have a good night's sleep.
Once the rain quit the trip was that much sweeter.
