Wing Down Method for x-wind
I suggest you learn this method, opposed to the crab, especially for the C152. The benefits are you have already set-up the x-wind controls on the approach (ie wing-down and opposite rudder to maintain heading) You have all of the finals to tune and adjust. It feels a bit uncomfortable as you are flying out of balance but it's no big deal.
The crab is still an important technique when flying low-wing types so don't abandon this method entirely.
It all takes practise so don't beat yourself up about it. We all make some duff landings.
But remember it's never too early to go around.
