All perfectly normal healthy reactions. Sounds like there are a few gaps in your training and also, remember that any new licence is really a 'licence to learn'. Also you may have had the relevant training but not absorbed it fully, or in need of reinforcement. But you figured out what to do at the time, and learnt from it. Genghis, as usual has good advice - Fly with an instructor from another school... tell them what happened and ask them to fly with you and work on some specific tasks. Things like spacing in the circuit , especially at an uncontrolled airport, one only learns after getting a licence and making a few mistakes. Its rarely wrong to extend downwind a bit for spacing. Or to fly a bit slower. Ask to be shown some of those techniques maybe ?
