Possible PTSD Diagnosis and Medication

If you stopped a medication cold turkey, it's possible you experienced withdrawal symptoms & those can definitely include psychiatric ones. &/or you may have PTSD. A psychiatrist or psychologist would be able to diagnose it based on the symptoms you are experiencing.

Be careful stopping meds suddenly..it can really make symptoms worse.understand that a lot of medications need to maintain a certain blood level to be effective.

I can't say if you have it or not because I'm not certified in any way to do so, however, if you believe you do have PTSD, do some research into different coping methods and see if you can find one that works. It's what I had to do before I got diagnosed.
