Christina Aguilera has days where she finds it difficult to "even get out of bed" since her marriage breakdown.

The 'Fighter' singer - who filed for divorce from husband Jordan Bratman last week - admits she has been finding it difficult to cope and is relying on her mother and close friends to help her get through the separation.

She told the December issue of Redbook magazine: "It's not easy, and there have been a lot of tears and sadness. It's impossible to redefine yourself and your life overnight. Thankfully, I have my mom and a small group of close friends who are there for me 24/7 and whom I can trust and depend on.

"On days when it feels impossible to even get out of bed, much less function as a mother, their support and encouragement have kept me moving forward."

Christina explained her only concern right now is trying to ensure her two-year-old son Max is not badly affected by his parents' split.

She said: "Thankfully, I have Max to keep me on a sane path. His needs and happiness are my top priorities, and my biggest concern is to protect him and make him feel safe."

Christina has refused to elaborate on the reasons for The Ending of her marriage saying "out of respect for my husband, I prefer to keep the specifics private. Right now, I'm just trying to figure out how to make it through each day".
