Aaron Carter addresses his health concerns and fears that he could be HIV-positive on the second part of a special two-episode edition of 'The Doctors' on Thursday.
'I need help, I'm scared,' says Carter in a clip from the episode obtained exclusively by DailyMail.com.
The 29-year-old singer then states that his 'greatest fear' is 'not being able to live,' shortly after it is revealed that he weighs just 115lbs fully clothed, a shockingly thin weight for an adult male who if 6ft tall.
His weight is part of the reason he believes he could be HIV-positive he says, telling the show's hosts: 'Because I'm so skinny, I'm still so skinny. And that was the biggest one for me.'
The US Department of Health states that a healthy weight range for a man Carter's size is between 150lbs and 190lbs, making the former pop star at least 25lbs underweight.

On Wednesday's episode, the troubled pop star detailed his frequent cosmetic surgeries and need for painkillers, admitting that when he cannot get a prescription he will obtain drugs illegally off the street.
He discussed his constant trips to the dermatologist as well, saying: 'I get fillers. Restylane, Voluma, Rejuviderm. I get all three, and I'm going to continue doing it. It makes me smile in the mirror.'
Carter's smile then quickly turned to tears however as he said: 'I see a pretty good looking guy, I'm just skinny.'
He then added: 'And I just want to get better.'
Carter spoke about the pills he has been prescribed by his doctors as well, which include Xanax and Oxycodone.
'I don't mix medications, I do it to release stress of pain or angst,'said Carter.
He later added in his sit-down interview with the hosts of the show that he does not want to be on these pills, and wishes that he was not buying them on the street.
Carter also admited that he had been forthright with his doctor about the fact that he is obtaining them illegally, and that he has nothing to hide.
'I have no problem telling exactly what it is,' said Aaron.
'The truth shall set your free and my father always said that.'
His appearance on the program comes after a tumultuous few moths during which he came out as bisexual and was charged with marijuana possession and suspicion of driving under the influence after an arrest in Georgia.
