Her mother, Teri. Employment?

I know that at one point Brooke said she started to manage her own career and dropped her mother. But also her mother was a hopeless alcoholic, so it made me wonder what did she do for a living after Brooke fired her as her manager. It's hard for me to believe she could have kept a job if she drank as much as what was reported. My guess would be Brooke was still supporting her until her death even if they were estranged.
