At the end of the day, you are your own primary caregiver.
Someone else may join you and even help you in that task, for which you should be so grateful. But, it is not their primary responsibility to care for you. It is your responsibility to care for yourself (which, by the way, enables you to be that much better off, should someone else join you in your care, too).
Just like it is not somebody else’s job to make you grow (or prevent your poor choices); that, too, is primarily your job.
When we take ownership of our well-being, we not only receive the benefit of doing so, we also enable ourselves to be in a position to offer care to others.
For too many, consenting to this notion is not an insignificant first step. But, once accepted, the tasks involved in what this means can form a rather long list.
What all is involved in true self-care? What does it even mean to be healthy?
...it is not someone else's job to answer those questions.
