Blog - still blog, may be your world has shrunk to the size of your garden, your flat, your bedroom. Blog - still blog, keep that life line, not just for you but for others. Even a small post on that silly thing your cat did/husband said/you saw on the internet will bring a spot of light to someone who is stuck at home. Stay in touch.
Create - if you can, create. Not for profit, but for you. Doodle, sketch, stitch, sew, knit, crochet.
Bake - nothing extravagant, something simple and have it with a mug of tea/coffee with the other castaways living with you. Warm scones (the BBC scone recipe is easy and quick) or easy biscuits are so comforting at a time like this.
Jigsaws - you know that pile of them you have stashed away? ... somewhere .... which you promised yourself to do? Seek them out, find them and find that simple pleasure of putting that final piece of the jigsaw in :D
Garden - if you have a garden - get out there - it is lovely here today. Potter on the patio, tinker on the balcony (none of these are euphemisms I hasten to add!!) Water the houseplants. Prune the bonsai, mist spray the climbing plants, sow seeds.
Talk. Ring that friend, message that work mate, text your cousin, send that email. Send it with love and support and you will get that love and support back.
Stay in touch xxxx
