I go through the same problems as well (dogs barking etc),Unfortunately I have come close to expressing my emotions through violence in the past. First comes the twitch then It feels like your losing a part of your mind and is replaced by an all consuming rage. It was at a diner and I was there with the two people I care about the most in my life. A large group of kids came in (age 19-23) and took the table in front of me and one across. They were really loud and vulgar... and this was in a family environment.I also have problems with being around people I don't know,plus the noise and being Hyper vigilant with the ptsd, well I came way to close that time.That was my worst time.
The rest of the time I spend hurting my relationships, What few there are.
