Arnold Schwarzenegger and Maria Shriver

Maria Shriver doesn't feel alone going through her separation from Arnold Schwarzenegger.
"Thank you for all the kindness, support and compassion," she wrote
to her Twitter fans on Friday. "I am humbled by the love. Thank you."
This is the first time Shriver, 55, has commented on her split, which Schwarzenegger, 63, addressed on Tuesday
, one day after the longtime couple announced their separation
in a statement.
Said the actor-politician at the time: "We're extremely blessed to be surrounded by so many wonderful people [and] by so many wonderful friends."
