Hi,
I'm really sorry to hear that you are feeling so rubbish. I also struggle with anxiety around nausea and I know what when I feel bad like that, it is very hard to think about anything else, so I absolutely sympathise.
I think the main thing to know is that baby is safe, and your body will deal with the flu, and will keep the baby safe.
It's really good that your temperature is normal. That is very good indeed.
The next thing is that you yourself are feeling anxious and in need of a bit of care and a feeling of safety. I think if you could find ways to help your body to feel calm and a bit better, that would really help.
Here are some things I do when I feel like that:
I listen to whale music on youtube, and that is really soothing and often helps to calm anxiety and stop the physical symptoms as well.
I make a hot water bottle and put it on my stomach to help relax the muscles and that really helps.
Sometimes I sit by an open french window or normal window, because the cold air really helps with nausea. If I do that at night I wrap a warm duvet round me to keep warm.
Sometimes I chew mint gum, which really helps.
Sometimes I fold the washing that has come out of the tumble dryer and that really really helps, for some reason. I think that just doing something like that with my hands helps my mind to be calm and then the physical symptoms subside.
The other thing is that it's really good to write a list of things that you might actually be anxious about in real life, so that when you feel calmer you can think about how to tackle some of those problems. If you write them down now, then you can forget about them for tonight.
I would second what the pp said above about accepting a referral for help with anxiety. I saw a lovely private psychologist for ten years and she helped me very much indeed. She left private practice last year and joined the NHS perinatal MH team, so if you were in the same area as me you might see her. She really was absolutely lovely and would be so much help in calming your worries.
I hope you manage to get comfy tonight. Flu can be so rubbish, and I feel for you sitting there working through it. It will go soon, and you will feel much much better.
Take care there.
