I'm so sorry for your loss, and I can understand the feeling of not getting better.

It would be a good idea to see a therapist and a psychiatrist, and if they do diagnose you with ptsd then they can find ways to help you get better. It's a long, slow road to recovery with ptsd, and I'm still working my way down that path, but it can get better.

Like said above, please post your worries anytime, and if you need to talk I'm here.
