I used to worry a lot about it and tried to hide a lot of what I was going through from my girls. A friend told me that for them to see me going through rough times and struggling my way through and not giving up was a good thing for them to see. And live through with me. That it would teach them that hard/tough times aren't the end of the world, can be gotten through with persistence and life does go on after the worst. When I've felt like I may be causing them too many problems by having a parent with PTSD, I remember this.

Hope it helps.
