Thank you to tinselworm and cryforthemoon for your lovely cards! I also received a card today (not from anyone on here) that had a stamp blatantly cut off something else and sellotaped on with the previous patch of envelope visible underneath it LOL. The Post Office didn't seem to object though.
In other news: still meh. Better than I was, but still in the realms of feeling unspeakably awful. Thanks to everybody who sent good wishes, they are much appreciated!
I'm sure there were other things I was going to write, but my brain's still not working properly *swoons waifishly heavily onto sofa*
