Emma Louise Ney, 41, was sentenced to 11 years and eight months in jail in March 2011 after being found guilty of the manslaughter of 52-year-old Graham Haynes in April 2007 at the couple's Acacia Ridge home south of Brisbane.
Ney hit Mr Haynes three times on the head with an axe, leaving him in a coma for two days before he died.
She appeared in Brisbane Supreme Court on Tuesday via videolink and told the court she would be representing herself in the bail application as she had not been able to contact Legal Aid during her five months in custody.
Justice Peter Davis told Ney that the crown prosecutor had described her as an unacceptable risk of failing to appear at future court hearings and committing further offences while on bail.
Ney said she had written letters to 13 drug rehabilitation centres to see if she was eligible if granted bail.
"I do have other residential addresses I could go to but the (Director of Public Prosecutions) has said they preferred I go to rehab, so that's what I'm focusing on," she said.
Ney said she had been diagnosed with psychosis and other mental health conditions.
"I feel like I'm at a dead end. I can't help myself. It's frustrating. Not getting the right mental health treatment. They have taken me off my medication. I'm suffering," she said.
"I know that I'm going to have to go to hospital because of the way I'm feeling."
The prosecutor said an indictment against Ney for allegedly wounding another person by throwing an object at them and causing a "deep laceration" on their chin had been "substantially considered" and was ready to hand down in the next few days.
Ney also faced charges of unlawful damage, public nuisance and dealing with suspected stolen goods dating between May and June 2022, and two counts of failing to appear in court.
Justice Davis said the problem with Ney's application was that she had a "very bad history" of breaching bail with more than 20 instances on her record.
"(Ney) is not in a good way, frankly. She has a drug problem and also has mental health issues. Fortunately as credit to her she has insight into these issues and has sought rehab," Justice Davis said.
"She desperately needs a lawyer to help with her application and she also needs assistance in attempting to secure a residential space inside a clinic.
"She needs assistance as soon as possible. I urge Legal Aid to give this lady's application priority."
Justice Davis adjourned Ney's bail hearing to a date yet to be fixed.
