I have actually tried to go against when I realized some of my behaviors. I did some thing I was not even aware of doing. ...I also realized at later times that I was so tensed a lot of the day. I have tried changing it when I go out. ..but it would not last long. I think if I were persistent about it though I could change some things. I would tell myself its ok because I makes me feel more comfortable and safer...and there is nothing wrong with that. REALLY???
Like another said...ITS EXHAUSTING...I use more energy tiring myself out always being like this.

I am more sensitive to sounds, bangs, thumps. Even soft thumps like people walking. To a extent I do not think its bad being hypervigilant. The senses are up and your more aware. Its a good thing...but I think we have to be more in control and need to find a way to relax.
I cannot change things about sound. I have tried in every way shape or form. Even shifting my mind and thoughts to loud sounds etc.

If this happens...nothing you can do about it...its a damage in the nerves. Its like a wound it hurts.
I find myself standing on the outskirts of places if I would go to a local event or place where there is much activity.

I have had unexpected people walk up on me and I bout to jump out of my skin...my heart actually hurt as is was racing beyond its limits. People have done it jokingly and it sent me into tears, as I tried to conceal them. I try to just laugh it off and joke about it and tell them jokingly they can't do that...they say sorry yada yada ya...
but its just before that point of reaching a panic terror but not going there...

The only thing I know ...these things taking place are temporary. It does take a tole on the body though...and it is exhausting.
When you get back or can find a place. Just give yourself permission that its ok to rest and relax your body. Even if you have to go somewhere else because the chaos is at home.
