Your doing just fine YA... keep going the way you are, because I think you can already see changes within yourself, I can anyway, but it does take years before you will for the majority of the time, be past it all, if you work at each symptom, each trauma. It does get better... but it doesn't happen overnight, in a few months, or even a year... it takes time, but continuous work and effort on your behalf, great support, you will get past the worst of PTSD. Then you just have to maintain it... thats another challenge in itself, but nowhere near the hard time to get past the bulk of the issues.
Hang in, keep your head up, and keep pushing yourself further and further, even when you don't think you can, thats when you need too.
