I've name changed for this as I'm easily ID'd in RL under my usual name.
My father died suddenly when I was a teenager and, for a while afterwards, my mum was in a very bad place where I feared for her safety. Everytime she went out I worried that she wouldn't come back. When I met DH I transferred all this worry on to him. If he was at all late I'd be convinced that he was dead and end up raging at him the minute he stepped through the door.
After a concerted effort to keep those thoughts at bay, I finally calmed down and started to relax when he went out but now I can feel those thoughts coming back but relating to the children. If they go anywhere with grandparents I worry there'll be an accident and if they stay over I fret about carbon monoxide poisoning.
I've started crying over stupid little things (yesterday I had to call the bank and was put through to the wrong number which made me cry!) I've started a new job at a call centre and probably one call in 100 will be someone shouty and that sees me in a side room sobbing. Then I'm worried for the next 10 calls that it's going to happen again.
What can I do to get a grip on this worrying?
