Is it my family is or are?
We typically say and write family is (not family are) in American English, treating it as singular, like other collective nouns.
In British English, it is very common to use are with collective nouns (even in formal contexts) if the writer or speaker is thinking of the group as individuals rather than a single entity, (e.g., The family are all very health conscious). This use is not common in American English, but it is acceptable.
