Barbara Hoekstra from Lake Shore Behavioral Health in Buffalo said feelings of uneasiness or fear are to be expected.
Each person copes with their feelings differently. Some may experience problems sleeping, lack of appetite, tiredness, or irritability.
The key is to continue your daily routine and don't be ashamed to seek help.
"These reactions and feelings are completely normal," said Barbara Hoekstra, RN from Lake Shore Behavioral Health from Buffalo. "People should absolutely seek out help if they need to."
When it comes to children, experts suggest limiting the amount of graphic videos they watch on television and online. Parents should also answer any questions they may have.
As horrific as yesterday's tragedy was, it is also an opportunity to highlight moments of bravery and self-sacrifice.
"In the midst of this disaster when it was clear something was happening out of the norm, people ran to help. Volunteers ran to help," said Hoekstra.
