She told us we were lucky that she hasn't put anti-freeze yet in our drinks, because she has it in her car in her trunk, she is beyond reason and refuses to be treated or get help, she is currently being held on a Baker Act but my fear is her wrath when she comes home and that she will not continue care, I will not allow her to continue to live with us unless she is being treated by a doctor. I am beyond stressed I have no time for myself in the evenings as every night is a new battle it is like living with Jekyl & Hyde I have gained weight from the stress, ALOT of weight, I am not happy and this is not fair to my son or I. Any suggestions? I need to get POA on her also ASAP.
This is someone who needs professional caregiving.
But neither did you ask for this, and you certainly can't control it. Tell the discharge planners that you cannot take your mother back into your apartment. You are not qualified to care for her and you must protect yourself and your son from her threats. Be firm.
I am sorry this puts you in a financial bind. That you were willing to take a chance and try to provide a comfortable home for her speaks highly of you. You did the right thing for what you knew at the time. I hope the financial hardship is temporary and you can quickly downsize again. But even the financial hardship does not override the sensible approach here: Do not make your son share his home with this mentally ill person who is violent.
There is no "bad guy" here. This is no one's fault. Continue to love your mother, advocate for her care, visit her often, and do not put yourself and son at risk.
The cost of the apartment is irrelevant. The safety of the child is paramount.
