Hi,
With everything in the news, something in me has altered. Now I'm scared in large shops - going in and instantly checking for exits, nervous standing by windows, scared of group gatherings...I had problems in a shop yesterday of my heart racing and videos playing in my head of what could happen. Noticing I was closely looking at people making sure they seemed decent. I'm using meditation to get to sleep and sleeping well, but daytime are proving difficult. In that shop I grabbed a few things quickly, didn't want to linger and felt a rush of relief once I was out. 
I've turned off the news, removed myself from Facebook news businesses and all the political accounts I followed before, stopped listening to phone-in talk radio and put on radio 4 for the comedy and drama. What else can I do? It's like nothing I've ever experienced before.
Now I am thinking, I have always had a very 'on' alert sense to possible danger like smoke smells, but haven't felt this bad and always been fine once I've seen it's safe. Do you think it's connected? I have a ridiculously vivid imagination and right now, I wish I didn't.
My children are enjoying being absolutely showered with love, kisses, cuddles and all the nice things they want, but my mind continues to work overdrive and it's very hard to keep working on not thinking such awful things.
Any advice please? Maybe everyone is feeling like this?
