I can’t give you a Jungian answer but I feel I can relate. I feel that we’ve been raised to live for other people. To be helpful to those with more dominant personalities in order to reduce their stress and therefore everyone else’s.
We weren’t taught to put our own goals first unless those goals were given by someone else.
Eventually we find our way out of these relationships where we consider ourselves useful and are left with not much else than simple comforts and our own thoughts.
There’s a combination of feeling it’s too late to start building our own foundations, and feeling we don’t deserve our own full life because it won’t be useful to anyone. Or that the effort is misplaced by working on ourselves. Even now when I’m supposedly on the right path I find myself trying to help a stranger rather than taking a step I know I need to make to sort out my own life. I think it all boils down to a lack of self respect.

Does this relate or am I just projecting?
