Reading re many people catching #Covid seemingly at the recent #Eastercon is making me more doubtful my husband and I can go to #Worldcon in #Glasgow in 2024. I'm severely #immunosuppressed, huge risk for Covid. We've been #shielding for most of 3 years to protect me. Not caught yet. We'd wear #masks but if too many other people don't and are infectious the risk of us catching is too high. With my medical situation it could kill me. We are both paid up attending members (reduced Scottish rate).

I feel this so much.
I’m #immunosuppressed and have a situation in my family like this.
II’m heart broken
I’m ok not socialising, we’re used to it now and we’re #introverts But what about family members who thrive on socialising?
Can you ask them not to socialise if they’re in their late teens or 20’s? When life ‘is’ socialising?
But their socialising could cost me my life?

Counting both the start date and today, this is my 1000th day of #shielding due to being clinically extremely vulnerable (#CEV) to #COVID19. There seems no end in sight with the lack of mitigations and consideration of the #vulnerable. I do wonder how long my sentence will last, never imagining it would be this long when I started.

The text "1000 days of shielding due to being clinically extremely vulnerable to COVID-19" appears above an illustration of the virus, created by the Centers for Disease Control and Prevention, showing the virus' spiky, crown-like fringe that shrouds each viral particle—giving it a “coronated” appearance. The question "Will it ever end?" appears beneath

#Introduction

As my biography states, I'm clinically extremely vulnerable to COVID-19 so have been #shielding since 7 Mar 2020

I'm a widow with no children having opted not to risk my late husband passing on his mutated ‘huntingtin’ gene. Sadly his sister's children both inherited hers

I've traced the gene across 5 generations with confirmed diagnoses and circumstantial evidence going back to William 1777-1854 as earliest source so far!
