Narrative:

While descending to land at sbp, I spotted traffic very close at approximately my 2 O'clock position. I immediately climbed steeply and believe the other aircraft passed below me or slightly aft of my position. I then descended after ascertaining the other aircraft was clear, and reported the incident to the tower controller who was very busy at the time.
