I am sorry you did not get the help you needed by people who are supposed to be professionals. I had to do a lot of research on my own too. Luckily, I do have a good therapist now, but I did go too long "without" the right help and support.
PTSD is still being studied, they don't really have all the answers yet, you are right, often the answer was "drug treatments" and people were put on several medications.
It is not unusual for a person to get diagnosed with Bipolar and GAD and a list of disorders when everything that is listed is all one thing PTSD.
I will say that a lot of the war veterans are using medical marijuana for their PTSD.
I am sorry that you have felt so betrayed, it's the last thing someone who is struggling needs.
