I can relate to a lot of that.
I was diagnosed with breast cancer 13 years ago, I was only 43 at the time, I had a lumpectomy , chemotherapy, radiotherapy and 5 years on Tamoxifen.
I'd had a hysterectomy 4 years previous but retained my ovaries the reason being, ironically, was because I couldn't have HRT due to a family history of breast cancer.
I lost my mum last September, to Parkinson's disease, the end came very suddenly and I wasn't ready ( although you never are ) I spent 4 days and nights at the hospital with her in her final days, along with my brother and sister, we never left the hospital.
I was completely devastated and am still grieving now, I've had counselling for bereavement which helped a little.
Then in June this year I lost another family member.
I think that loss plus attending the funeral triggered everything again for me.
My anxiety got worse, so dr took me off Trazadone cold turkey, big mistake, I started on Mirtazapine at 15mg and wasn't too bad but when it was increased to 45mg my anxiety heightened out of the window, I had severe panic attacks, couldn't eat, non stop shaking, it was horrendous!
I was referred to a mental health nurse specialist at my surgery who put me on Escitilopram as he said it was the gentlest SSRI , my GP then added Quetiapine too as I was in crisis.
Took a while to settle, and although I still get anxiety it's not as bad.
I still find it difficult to attend social events and usually cancel, making some excuse as to why I can't go.
We had to cancel a holiday to Portugal in September this year as my anxiety heightened again at the thought of it.
It was only two weeks before that I'd managed to catch a bus for the first time for ages!
Be kind to yourself and don't beat yourself up about things you can't do, that's what I've been told.
Sending you hugs 🤗
