As my instructor used to say - you don't know the meaning of lost until you're lost at Mach 2.5...
You talked to somebody and you got home without bumping into anyone / anything. You've now used D&D for what they're good at (my practice pans / "unsure of positions" were only to an instructor) which is a good learning experience anyway.
You managed to pull yourself together to handle the situation so you did an awful lot better than someone who was prosecuted recently for getting lost, not talking to anyone then infringing the airspace of two major airports (his licence had expired too...).
Take it as a learning experience and get rid of that embarrassment. You should try to take positives from it - that you got back in one piece on your own without D&D needing to get someone up after you to escort you home (which happened in Glasgow not that long ago too).
As others have said here - Well Done and Keep Flying!
