As Britney Spears entered rehab to deal with her mental health issues amid her father’s health problems, her family and friends have rushed to her side to show their support. Britney’s father’s health is a state of concern for the singer as he has recently undergone a second surgery for a ruptured colon with reports indicating that his health is declining.

Britney checked herself into the mental health treatment facility at the urging of her father, Jaime Spears, as a Radar Online source said, she “means so much to him” and he wants to know that she will be alright.

Her mother, Lynn Spears, took to Instagram to give her daughter an emotional boost as she wrote, “Keep Going. No matter how bad things are right now, no matter how stuck you feel, no matter how many days you’ve spent crying. No matter how many days you’ve spent wishing things were different, no matter how hopeless and depressed you feel, I promise you won’t feel this way forever. Keep going.”

Britney’s sister, Jamie Lynn Spears, also had some words of encouragement for the singer posting a photo of the two sisters on their first day of school as small children. Both girls are smiling in the photo as they head off the school bus.

Jamie Lynn captioned the photo, “Yup, she rode the bus home with me after my first day of school, cuz she’s the [expletive] best.”

Britney’s boyfriend Sam Asghari also showed his support for the 37-year-old by posting a quote that is meaningful to his girlfriend as she previously posted it herself. The quote read, “Fall in love with taking care of yourself, mind, body, spirit.”

Asghari captioned the quote, “ It isn’t weakness , It’s a sign of absolute strength, people should only be inspired by this, at least I am. #stronger.”

Even Britney’s ex-husband, Kevin Federline, showed that he is there for her as he too as he expressed his support for her current situation through his attorney March Vincent Kaplan, who told The Blast, “Kevin commends Britney for recognizing that she needs to take a step back and that she is taking the reasonable steps to deal with her situation in a responsible way.”

Federline has 90 percent custody of the couple’s two children while Britney is in rehab, which is expected to last for the next 30 days, Radar Online reported. She checked into the facility a week ago.
