Diana - thirty years later I am *still* dealing with the emotions caused by my family laughing at my singing; though intellectually I know that the people who tell me *now* that my singing is okay *are* telling me the truth.

Ignore the family.

The boyfriend may be biased; *grin*; but since he is encouraging you *don't* ignore him.

The teacher should be able to give an unbiased critique - you might ask for a review - what are my weak points, what are my strengths type thing.
