Hello.
Thanks for using DoctorSpring.com for posting your query.
I have gone through your question in detail and I can understand what you are going through.
The diagnosis of PTSD and depression is very troublesome for the patient and you seem to be having a lot of distress with the symptoms. Now the only thing that can help you is medical therapy and psychotherapy. Medical therapy involves sedative antidepressants such as Mirtazapine or Paroxetine. The sedative antipsychotics like Quetiapine or Olanzapine in low doses can also work well. Among the hypnotics, if nothing works then giving Diazepam directly may also help.
I am not sure if your psychiatrist has explored all these options.
Also, in PTSD prescription of Clonidine at 0.1 mg TDS, may also help in reducing hyper-arousal and inducing sleep.
Among the newer therapies, Ketamine has emerged as a good option for such resistant cases where the above treatment does not work. Infusions of Ketamine are being used these days with successful treatment of anxiety disorders.
Among the therapies, I am sure your psychiatrist may be already trying the behaviour and cognitive therapies. You may also insist on EMDR (Eye Movement Desensitization Reaction) therapy which is also helpful in dealing with the residual symptoms of PTSD.
Hope this was helpful. If you have any further query, I would be glad to help you. Wish you good health.
Kind regards,
Dr. Srikanth Reddy MD.
