For a couple of months I've been feeling kinda off like something isn't right, I constantly have a feeling that my heart is always racing and it doesn't let up. I also notice that I'm very unaware of any emotions and detached from them I guess. I also notice that I'm never blinking only when I think to blink, I blink I don't know if this is due to the PTSD or something else, its been going on ever since I was about 14. Any advise on any of this will be very helpful
