I did help a young lad about your age when I was on my way to my bike club, he had a puncture kit but no tyre levers or spanner so couldnt take his wheel off or access his inner tube.
I had levers so we managed to get the tube out of the tyre and patch the puncture which was very obvious and a big hole.
I then pumped it up for him and sent him on his way with advice to purchase a spanner or tyre levers at least.
Saved him a long walk anyway
