How to deal with doom-y thoughts

Sorry to hear that CarrotTop and especially for the way you were treated in A&E🤬 I have personal experience of that recently which mirrors yours.
Have you seen your old GP yet to tell him/her of your distressing ailment?
It’s understandable that you feel a sense of impending doom as you need to be well to take care of your DH and run things.
This episode has brought this home to you.
All I can offer is to be kind to yourself💐

I have no experience of these feelings, but I didn’t want to read and run. I am so sorry that these things have happened to you both. I do hope things get better, physically and mentally for you both. Life can be very hard at times, sending hugs.

I haven't posted for a while but maybe if this helps here goes. I know exactly how you are feeling. My life has been tough as many are. I thought things would now be ok. How silly of me.

Last month, on holiday, fortunately not far from home, I fell top to bottom down a flight of very steep stairs. Fortunately no bones broken but a severely cut head. The blood was unbelievable. I was taken by ambulance to A&E. They were wonderful there but the experience has left me traumatised.

I lost all my hair some years ago and wear a hair system. I have always dreaded something happening to my head and my system having to come off. My DH used to say 'stop worrying about things that will never happen' and yet there I was, hair system off, it and me soaked in blood, humiliated and scared. My husband had never seen me without my hair system. It was horrendous. I am still in shock and I know that doomy feeling you describe. I have had many horrible things happen but this awful feeling of dread and shock won't go away. I hope things improve for you.
