It's kind of hard to say what normal is, normal from the people who see you occasionally, or the friends that see you really often, or your family who knows the days when getting out of bed, or cleaning the house is an impossibility for a week?
For me, when I go out with friends, which isn't all that often, I look fine, I act fine, and everyone was surprised when they heard I was diagnosed with PTSD.
But for me, I act fine, and yet I am constantly aware of everyone around me, and people constantly brushing up against me in a crowd makes me jittery as hell.
Walking to the shops is a big deal that I have to prepare for, cleaning the house fills me with dread, and when friends come over, the house is up to my old standards, but only because I got in a cleaner to help me.
Normal for me, is how I feel on a particular day compared to the best I've felt recently, and how much energy accompanies it, because I may be mentally alert, but my body will be dragging far behind, or my body is ready to bounce, but my brain lags so far behind that I bounce into the nearest object!
