I know you didn't come here for criticism, which I'm not indenting to do.
However, if you passed a PPL by map crawling and not DR 1/60 navigation, your ATO needs a swift kick up the butt.
You obviously don't have confidence in navigation still, so good on you for seeking out assistance.
As discussed, you need to really start researching 1/60 navigation and then practice those skills with someone who can guide you along.
Dead reckoning navigation is all about getting yourself off track, and being completely fine with that. If you were flying from A to C and the map shows your going directly over B, 9 times out of 10 you won't fly directly over B - and that's completely okay.
