Amanda Bynes has been on a public down spiral for a while now, she was arrested for a DUI back in April, was charged in two hit-and-runs,  and then spotted driving while smoking out of a weed pipe. Now people that deal with Amanda on a daily basis are saying something might be wrong with her mentally. According to people at her gym, Amanda has been seen having full convos with herself and having crazy, laughing fits. Amanda’s neighbors have also said that the actress has been known to have long conversations with innate objects. Someone should step in and save this girl before she pulls a Britney or kills herself via car crash or drunk overdose. Read more below.

Amanda Bynes has much bigger problems than smoking pot and driving illegally … there’s evidence she has serious mental issues.

TMZ has spoken with a number of people who have had repeated contact with Bynes over the last few months, and the stories are consistent and disturbing.

Several people from her gym — Equinox in West Hollywood – tell us, she has been showing increasingly alarming signs of delusional behavior. One person says Amanda came to the gym Thursday looking dazed and began speaking with herself — making comments and then answering back.

Another person says when Amanda was on the elliptical, she would stop suddenly and start “laughing hysterically for no reason.” She did this periodically throughout her workout. This person says he’s seen her dozens of times in the last few months, and says it’s apparent her condition is “deteriorating.”

Several of Amanda’s neighbors echo the concern over Amanda’s condition. One tells us he observed her on several occasions having long conversations with inanimate objects. Another person says people in her condo complex are aware of her condition and her conduct but haven’t called her friends or relatives or authorities because they just don’t want to get involved, given her profile.

Some of the people in the building have been upset over the last few weeks, because they believe the media is painting Amanda as a garden variety pothead and they say her problems are much deeper.
