As a person with PTSD I know How you feel when people will not listen to you or even try to under stand were your at. What I Did was went to my Doctor and picked up some pamphelet's on PTSD and My other mental Illnesses and laid them around the House. eventually my family picked them up and read them. I also noticed you said your Daughter drew you you a picture of a cloud with a sad face and tear's. I would think you could connect with her by every day drawing her a picture of how you feel about her or what kind of mood your in. And as a military person we are taught not to give up. Don't give up on Life or your Family seek some help and keep coming back here and talk about these thing's their are people here that are going threw the same thing's.
