I'm with raging vortex...I stay active here on the forum. It's a 24/7 support group and a chance for me to help others, too.
Sleep hygiene is primary for me. The other basics...being clean, presentable (even if I'm all alone), health care.
Music is essential for me. Allowing myself the pleasure of relaxed reading (books).
A big self-care is getting my hair done, whether cut/style and/or color.
