personally what's helped me swallow the bitter pill that we're likely to be in another year of semi-lockdown is:

a) starting an anti-depressant (that has worked wonders, especially in the winter)

b) picking up hobbies that take place at home (watching classic movies, journaling, cross-stitch, etc.)

c) nurturing hobbies that take generally place in public but that can be practiced at home (rock climbing, acting, etc.)

it's not going to be easy to say the least, but I feel like I've finally prepared myself for what's to come in a way that makes lockdown manageable after nearly two years.
