What were Meg’s feelings about her father, brother, and Calvin after escaping from IT? Do tou think should felt this way?

Meg begins to question her father’s judgment of tessering her and Calvin away and leaving Charles Wallace behind. Soon, she fills up with anger, realizing that "she had found her father and he had not made everything all right. Everything kept getting worse and worse.” Mr. Murry tries to console her and tell her that he is not a perfect person, but Meg only gets angrier and angrier and accuses him of almost letting the Black Thing get her. I think Meg is just frustrated, she doesn't understand the mental and emotional strength that her father and brother were under.
