Hello I believe I can help you with your issue regarding your daughter
I would like to ask some questions to understand your daughter a little bit more
How long has she acted this way (e.g Paranoia).
And has she ever sought out therapy or taken psychiatric medication?
Here is a link for the criteria of borderline personality disorder to give you a more detailed look at the diagnosis
There are a number of things that can help your duaghter
There are clincs and shelters out there that can provide services and possibly shelter for your daughter
It definitely seems like you want to help her and I understand how much it must pain you to see her like this, so you can co-sign a lease for her if you wish, but do it based on a requirement that she seek mental health counseling.
If she really does have Borderline Personality Disorder, then a therapy called Dialectical Behavioral Therapy (DBT) can help her greatly. DBT can also help with other emotional disorders as well like depression and Bipolar Disorder for example
In addition certain psychotropic medication can have an immediate impact and lessen the severity of her symptoms, so that she responds better to therapy. So an appt with a prescribing physician may help her, and there are some free clinics or women's shelters that can provide this service
For your daughter to help reduce her stress, I am attaching a link that may provide her with some self-help techniques designed to reduce stress
Stress has the ability to increase the severity of mental health symptoms in most people, so that is why it is ideal for her to reduce her stress.
And finally with your medical health issues, I dont think it would be wise for you to over extend yourself because you have to look after your own health as well. If your daughter will not at least meet you half way or causes you serious strain on your mental and medical health, then it may be appropriate to escape the situation and allow your daughter to make her own choices and live with those consequences without you in her life
I know that sounds tough, especially because you are her mother and care immensely about her, but I only want you to consider it for the sake of your health
If you have any questions or concerns, please do not hesitate to talk to me and I will get back to you as soon as I can. I hope I provided you with excellent service today.
