Dear concerned boyfriend, I can understand why you’re worried. Your girlfriend’s symptoms are severe. The most concerning aspect of her behavior is that on several occasions you found her with a cable wrapped around her neck ready to end her life. It does not seem as if she’s depressed. It’s as if she’s being driven to behave in such a manner by her delusions, paranoia and hallucinations.
Her symptoms may be indicative of a schizophrenia or bipolar-like disorder. It may also be a generalized psychosis. It’s difficult to diagnose an individual over the Internet so I can’t know with certainty.
If I could ask you followup questions I would want to know what, if anything precipitated her symptoms. Was there a stressful event that had recently occurred? Was there a recent trauma in her life? Did something in her life recently change? Was there a death in the family, loss of a job, or a move to a new town or city? Does she use illegal drugs or alcohol? Has she had a recent head injury? If I knew this information I might be better able to determine what is causing her abnormal behavior.
You also mentioned that she has recently stopped taking Paxil. Though it is rare, there are some occasions when abruptly stopping a medication causes a negative reaction. Usually these negative reactions are more commonly associated with other medications such as antipsychotics and not necessarily antidepressants. As I’ve mentioned, it’s rare but it’s possible that her behavior is the result of the discontinuation of Paxil.
Has she been to a doctor? It is unsafe for her to be left alone while she is in the condition you have described. This is evidenced by the fact that she has made multiple attempts to end her life.
Please do not ignore or avoid this problem. My advice is to bring her to an emergency room or to make an immediate appointment with a mental health clinician. She needs to be evaluated as soon as possible. Do not leave her unsupervised. Please let me know if there are any other questions I can answer for you.
