Has anyone managed to "get over" their symptoms to the extent they hardly ever even think about them, and how did you do it?
Yes, and plenty of others who have left here over the years have achieved significant reduction.
Its called, hard work and then good daily self management. Everyone is different on severity... I am diagnosed as severe, and providing I manage my stressor intake day to day, I can remain quite symptomless. If I don't manage it and am exposed to more stressors than I can take, I become quite ill, quite quickly, however; I also recover in much quicker time frames now than I did many years ago... along with my responses and actions are much healthier now compared to years ago.
You have to weigh up severity and what is achievable. Some people only just meet PTSD, or have been diagnosed with it when they don't have it... so they recover fully and become a statistic of success. The truth though for those that really do have PTSD, not just post traumatic stress, is that what you endure daily symptom wise can be significantly reduced to provide less impact upon your daily life. For most with PTSD, if working as well, you will be medicated to work more than likely, thus have symptom issues regardless even with medication, because daily management is not occurring, and instead suppression occurs via medication. So you will still eventually blow and fall down again.
You have to review success on how you cannot function when ill, too what you would like to achieve. I couldn't go to shops, crowds, etc... I can now in limited bursts, providing I prepare myself mentally, I relax during the event, and reinforce things to myself in my head during and after, and I don't fall down. Sometimes I still fall down for a few days if an event occurs over days vs. hours.
When my own PTSD was out of control, I was extremely angry, very hostile, drunk, a relationship was just a f*ck, and the long list of being an arsehole went on and on... Now... I am nothing like that, as I never was like it prior to PTSD. PTSD brought out all the bad, I then changed that bad back into more positive behaviors.
Lots of daily management skills are required for severe and complex sufferers....
