You ARE doing well! You got lost, as everyone does once in a while, and contacted the right people to put you back on track. Better than I did at a later stage than you, in fact soon after getting my PPL. On my first longish trip I got lost, didn't want to tell anyone, floundered around wondering what to do, and it wasn't until I saw a motorway that really shouldn't have been there that I contacted D & D. They told me I was three miles from Birmingham Airport! How embarrassing do you think that was? But I survived, and learned.....oh, and I bought a GPS, which you can do as soon as you qualify.
Recommendations... Learn from it, then put it behind you and keep going. Don't feel bad; basic navigation is hard, and I don't think I know a pilot who hasn't been lost - and I know a lot of pilots! And above all, don't give up!
