Your daughter is mentally ill, and the “drama” is the symptoms of that illness that are not being managed. Unless she is managing them through the use of illicit substances.
Please keep the children safe from her. She is not able to parent, and most likely may not be able to independently parent ever.
It might be time for a family meeting to look into options for the future care of these children and your daughter. Legally, financially and morally.
Give her one number as a family contact, and block all others. Hang up when she is rude on the phone, call the police when she violates the order of protection.
When she threatens suicide, call the police and let them know she threatened suicide and needs help.
Let her children know their mother has an illness that causes her to not feel good, and when she doesn’t feel good she doesn’t behave very nicely and can be mean to others. When she doesn’t feel good, it’s best to leave her alone until she feels better. Remind the children she loves them, but her illness sometimes makes it hard for her to show it.
Her behavior (symptoms) are beyond your ability to manage. It would be best for your family to receive some professional help to educate yourselves on the progression of your daughter’s illness and realistic expectations of her going forward.
Sorry you are going through this.
