I had terrible anxiety last year - I couldn't make it into my kitchen without having a panic attack, had heartburn constantly, my blood pressure was doing silly things (I would start to black out when standing up). I felt like a rabbit in front of a predator, whenever I faced a challenge my brain would just power down and try to put me to sleep.
Here's what saved me:
I took some time out from normal life. I had to get on a bus because I couldn't drive, and stay with a relative for a week. It was drastic, but I had to 'put on my oxygen mask first'.
I realised that the anxiety was caused by a combination of current stress and past trauma and I used the time out to separate them by writing about it, listing things in each category, really tidying my mind.
I had to forgive myself for being weakened by the traumatic stuff. I had to look at it written down and say "Wow, that was a shitty, shitty time, no one should have to cope with that". And then I found I could shelve it.
I had to honestly look at the current stress, be brave enough to say "I hate this about my life and I feel helpless about most of it".
I had to ask for help for the things I couldn't change alone. A loan, more assistance from agencies, specific help from husband and new house rules.
I have been getting stronger and stronger since then, my anxiety is gone, I can face stressful days now, and I'm getting my old life and interests back. I hope this helps you, I had to hit rock bottom before I worked it out. You aren't alone, and I'm cheering you on.
TLDR
Take a total break if you can
You aren't weak or "ill" you are responding to trauma or stress in a natural way, and it can be resolved
Demand help directly, without any shame
