Hello merename. I feel for you - it is a lonely place to be. Hopefully the move into spring will help with people's moods. For me it makes such a difference to be able to sit in the garden with something to read, listening to the birds, etc. I'm lucky to have a peaceful garden, but even listening to the sound of passing traffic and people chatting soothes me. It's an existence away from the dementia I suppose.
Remember, much as we'd like them to, good things, good moods, good experiences, don't last forever. This means that, conversely, bad things, bad experiences can't last forever, because life doesn't work like that.
