Human Factors
Coming into ZZZ this morning I was instructed to look for traffic. I got a visual and radioed that in. Tower then told me to follow that traffic and that I was cleared to land Runway 28R; number 2 in sequence.So I followed the plane and then when I turned final I saw another plane below me pass me and land on 28R. I called Tower and told them there's a plane on the runway. They had me take an immediate crosswind turn to the right and cleared me to land again as the other plane was doing a touch and go.In the confusion; instead of retracting flaps; I had fully extended them when executing the go around. I was losing altitude even with full power and was below 40 knots IAS just a few hundred feet above a lake just north of the airport. Tower called to ask if I was OK.Finally found the flaps fully extended; retracted them; and landed without incident.I believe the airplane I was supposed to follow was a different airplane than the one I saw and followed. My guess is that the one I saw was operating on the parallel runway; 28L. I mistook that airplane as the traffic to follow and so turned to base and final too soon. Fortunately the airplane I was supposed to follow reached the runway before I had fully turned to final.
C150 pilot reported an NMAC with another small aircraft in the pattern.
