I'm new here. I just started dating a PTSD sufferer about two months ago. His symptoms were not manifesting when we first started dating and things were wonderful. He's struggling now, and he's completely different. I've been reading all I can find, and I watched the 18 short videos someone posted. They worked wonders for my perspective. Sometimes I just find myself at a loss when I don't know what he needs, and I'm not hearing much from him. I've heard the oxygen mask illustration-- that I have to take care of myself and be in good shape to be able to help him. Any tips on how to do that?
