Agree with all of the above...Student pilot or not,
you were the aircraft Commander and for whatever reason you decided not to land...what is really important now is not to dwell on this "incident". Whatever you do, do not let ATC's comments on the R/T or their phone call influence any future decisions you have to make.
Do you happen know what your school/instructor said to ATC? ( I know what I would have said
)
Oh, and you might want to consider having your harness done up a bit tighter.
