I got a shielding letter, due to autoimmune condition. I'm not entirely sure I'm at any more risk than anyone else tbh, but my doctor deemed me at risk enough to kindly add me to the register, so it's the least I can do to follow their instructions as much as possible.
I have been out for a walk most days. I live alone and was thrown into this situation just 4 weeks after I moved into my new house/life.
I go out very early in the morning and I don't see a soul. I don't need to touch anything between the inside of my own front door and returning from my walk, so for my own metal health, I feel I've risk assessed going out well enough for myself.
I did find the free food box very handy for a couple of weeks, until I managed to get a reoccurring supermarket slot, but I've cancelled it now, as there's just no need for it for me.
I sincerely hope I don't get a letter extending my shielding for another 12 weeks. That'll really knock me for 6. Although I work in a school, so I guess even if I can't go out, theoretically I can be assured my job is safe until September at least.
As for what anybody else thinks, I'm not the slightest bit bothered. People who know and care about me enough, know I'm not a shirker when it comes to work and I'm fiercely independent, so in fact they are more likely to tell me to do as I'm bloody told rather than question why I'm in this group!
