Normal to the injury is good to understand. And it's normal not to want friends because:

...I don't trust anyone

...In the end they, too, will be taken away

...Friendship means sharing and knowing about each other - and it ain't gonna happen

...I must then maintain for them also when I can't even maintain for myself

...I really don't care about their petty problems

...I don't want them caring about my problems

...They ask questions that are triggers

...They start caring about me dragging in sympathy, empathy, and wanting to help

...They would hate the person hiding behind the mask

...They admire my service and want to tell me and others about it

...They can't get it that I just want to be alone

...They don't realize that their happiness is a trigger for me, and their bright smile is a warning sign to me

...They'll never understand that I am always ready for the enemy

...They have no way of knowing how noises, bright flashing lights and crowds affect me (and that none of it is mental) no matter how much I keep telling myself that everything is all right

...They can't imagine the amount of energy it takes to keep the mask in place so that I'm socially acceptable
