Things might not be what they seem ...

Britney Spears completed mental health treatment a few weeks ago and has been out and about since then -- she's posted a message to her fans on Instagram that she's okay, despite reports she was being held against her will! And the logical conclusion that most fans drew was that Britney was fine after her brief hospitalization, and back on track, but a new report claims that might not be true ...

Us Weekly says a source tells them Brit's mom Lynne is NOT trying to help the singer get control of her own estate by ending the conservatorship -- on the contrary, she thinks her daughter needs even MORE help.

A source tells the mag: "Reports that Lynne is trying to help Britney loosen the constraints of the conservatorship are false. If anything, Lynne wants Britney back in treatment, and that angers Britney."

Lynne went to court with Brit on May 10 to request that the judge order a new psychiatric evaluation for Britney which is considered the first step in ending the conservatorship BUT another source tells Us Britney doesn't care if her dad -- the sole conservator since co-conservator Andrew Wallet ended his involvement recently -- has control over her finances, but he wants him OUT of her personal life. The source says, "Britney doesn’t care if Jamie is left in control of her finances with the conservatorship of the estate remaining. However, according to Britney, the conservatorship of her personal life needs to end. She is finished with Jamie having control of her personal life and wants to have her own control over that."

Meanwhile, ex Kevin Federline is restricting sons' Preston, 13, and Jayden, 12 visitation with their mom. A source tells Us: "Britney’s immediate concern has been in having increased visitation time with her boys,” a source exclusively tells Us Weekly. “Kevin won’t allow the boys to spend more time with their mother until Britney is once again stable and therapeutic on medication. He allows the boys to spend time with Britney, but it’s at his discretion."

We're a little worried, frankly -- check out the gallery of pix below of Brit driving the other day. She kinda looks out of it, right?!
