Don't lose heart .. it was a very busy day today especially in the South East of England.
When returning to my local field today I had to orbit once when approaching the overhead, then three times on the deadside whilst trying to get an RT call in for clearance to descend. Aircraft coming from all directions, some uncertain about the procedures were descending deadside without permission (always upsets the ATC) and with all this going on there are others expecting to do circuits. Takes all the fun out of flying when its like that.
Try flying on weekdays when its less busy and build your confidence up.
