The 22-year-old is reportedly struggling to cope since her affair with married director Rupert Sanders was made public, reported Daily Star.
"She knows she messed up so badly by cheating on him, and she's finding it hard to cope with her agony. Even though Kristen has close family and friends trying to be supportive, it's not enough.
"She keeps beating herself up, asking why, why, why? She knows she needs a professional to help her - it's like she's going through a divorce," a source said.
