I'm new to this forum and am after a bit of advice. A couple of weeks ago I woke up in the middle of night feely sweaty, shaky and my head was all over the place. For 3/4 nights after this I felt scared to go to bed and did not get any sleep for days. Finally I did sleep but on and off since then most if I wake at night I get a similar feeling but not as bad as the first. I find if I open the window for fresh air this helps. All this seems to have started since I had bad news about someone at work having a massive heart attack whilst driving. However, I don't think this is constantly on my mind but its making me feel horrible on and off.
