Why is Mary warren afraid to testify?

Answer 1

Proctor doesn't want Mary to go back to court because it will further involve him. He doesn't believe the girls who are making the accusations, but the court is being unfair and unjust to those accused.

Answer 2

Most probably, at that very time, she was afraid. She had once been abused by John Proctor by being whipped and on and on. But now, she going to help John Proctor?!? We must also view the situation from her point of view, should she stand on the side of John Proctor and testify, it may not be benificial to her personally, as she may have to be whipped. Similarly, she may been held for contemplation of court, should the Judge do not believes what she have to say. Hence, by deciding to act hysterical with the girls and stand on the other side, she does not need to worry about being on the wrong side, she can just remain mad, and that is all that need to be done. She had save herself from running risk. Its human nature that we are selfish and live for ourself.
The other girls
