You didn' get lost, you just went for a bit of sight seeing.
You used ATS to find you way home perfectly safely without (from what I have assumed) any infringements or problems. What you have show is the correct aptitude for a future pilot... You went wrong, realised this and then used the aids available to you in a timely and professional manner to rectify the problem.
Be proud of what you did, there are many students out there that will try and bluff it, end up on bingo fuel in class A airspace with a Typhoon on QRA saying hello (extreme example but it could happen all too easily).
Crack on and see you in the skies matey
