Self-care is something everyone should do at least once in a while as it gives us a break from everything and a chance to enjoy yourselves, here's some ideas you could do right now:
1) Reconnect with old hobbies, maybe you used to write stories or painted artwork - if not try out some new ones like gardening, painting, crosswords etc
2) Make weekly plans with loved ones or friends as loneliness can effect us all but it can be a real challenge for the elderly.
3) Give yourself a moment to rest, and simply just exist, do what you want to do. You could do some meditation, journaling or take a walk around a park.Our Gran Smile's gift hamper boxes are great for self-care, it has colouring books, snacks and a book to read among many other things.
