Rob Kardashian is trying to start over.
The reality star has deleted nearly all his Twitter message, along with his Instagram page, and is ready to lose weight.
The moves come just days after Rob shockingly peaced out of his sister's wedding weekend, catching a flight to Los Angeles Saturday morning... before Kim Kardashian said "I Do" for the third time.
Some sort of issue allegedly arose over Rob refusing to be included in any family portraits due to his low self-esteem.
"Friends at the wedding expressed serious concern for him," a close family pal, who attended the Kimye festivities, tells People. "When I saw him, it looked like something was very wrong."
