A few levels can make a world of difference...

I would try Merc's recommendation to go to Sunken Temple through 55 and head back to BRD at ~56 and do Vipeax's figure 8 until you feel like that is easy and then branch out.

Please report back what you decide to do and how it goes as it will help others...

Also try to look on the bright side...

You are in the home stretch and some of us are still in the 20s, 30s, & 40s...
