Casey Anthony -- Fixing Her Mental Problems ... From Home

Casey Anthony has decided NOT to enter a treatment facility for "obvious mental health issues" -- instead, TMZ has learned, she's getting professional psychiatric help delivered right to her front door.

Sources close to Casey tell TMZ, she's concerned about leaving her Florida home -- where she's serving a year of probation for her check fraud case -- but Casey still understands she needs mental help.

The solution ... we're told Casey has hired a team of mental health professionals to visit her on a regular basis.

But it doesn't end there -- we're told Casey has also employed the help of a spiritual adviser to keep her centered.

As we previously reported, sources close to Casey tell TMZ, Casey attributes her bizarre behavior when her daughter Caylee went missing back in 2008 to "obvious mental health issues."
