continuing grief over the death of her mother is putting a huge strain on her health, the actress' brother claims. Jolie's mom Marcheline Bertrand
passed away in January after a long battle with cancer. The A Mighty Heart
actress recently broke down in a TV interview as she spoke about her late mother, and brother James Haven Voight is worried Jolie is letting the bereavement take over her life.
He tells British magazine Closer
, "She exhausts herself and at the moment she has a very low resistance level because she misses our mother so much and just longs for her all the time."
Voight also reveals Jolie's visits to less developed countries in her role as a United Nations ambassador has significantly affected her eating habits.
He adds, "Angie visited Ethiopia and it changed her life. It's hard for her to go home to a very expensive restaurant and order freely."
