Just when you thought Amanda Bynes couldn’t make herself look any crazier, she goes and locks herself in a dressing room for almost two hours.

No, really. That’s what she did, according to TMZ reports. And their description of the events are so unbelievable that it would be totally wrong for us to re-word it in any way. So here it is:

Amanda was shopping at Kin (above) — a hip boutique. Amanda took some clothes inside the fitting room and stayed for 1 hr. 45 min.

The clerks heard a banging sound coming from inside the dressing room every 10 minutes or so. One clerk made a distress call to another employee, saying he was concerned about Bynes being holed up for so long.

The employee drove to the store to help, to no avail. Amanda wouldn’t come out, telling them, “I need more time.” Amanda finally came out at around 5:30 PM, went to the register and bought a pair of stilettos, a pair of sunglasses and a few other things.

Now get this … as Amanda walked out she noticed she had tried on a bathing suit top that was underneath her dress and told the clerk she forgot it was on. Amanda then paid for the suit.

Amanda saw a few photogs before leaving and then asked the clerk to call her a cab. It’s unclear how she arrived at the store.

Afterwards one of the clerks told someone, “I was so worried about her. I didn’t know what she was doing in [the dressing room]. I didn’t know if she was overdosing, or doing drugs or what.”

Hey, it could have been worse. At least she wasn’t driving. But that’s kind of difficult for her right now anyway, seeing as her car was just impounded Sunday morning (Sep 16) after she was pulled over driving illegally on a suspended license for the umpteenth time. (See below)

Meanwhile, Amanda is telling her friends, who are telling TMZ, that the stories floating around the Internet about her being a total nutcase “are being blown way out of proportion,” and she’s about as sane as they come. (Riiiight)

TMZ, after speaking with several people who have unfortunately been in Amanda’s presence recently, reported this weekend that Amanda is evidently suffering from “serious mental issues.”

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.

See. You might be inclined to call Amanda Bynes crazy, but get her some good meds, a conservatorship and a full-time babysitter, and you could just call her Britney Spears.

Amanda Bynes is right. She isn’t crazy. She just needs serious mental help.
