5s as parents…how do you deal with the constant battle with your basic fear

I’m wondering how 5s that are parents or have chosen to be parents manage with those obligations and realities given our type.

I’m in a position where I’m pseudo parenting my much younger sister and cousins. So I’m not parenting by choice but I’m interested to see how y’all actually get to a place to make that choice and deal with the day to day internal turmoil

I often find myself 1) feeling deeply overwhelmed at the load 2) occasionally feeling a kind of avarice and resentment around the demands on my time, energy and finances 3) deep uncertainty as to whether the decisions (or lack thereof) I make on their behalf are good and will positively impact them 4) the rules and influence I set/impose are actually good

I’m quite certain that the above, for me, comes primarily from being a 5 (sense of incapability, incapacity and incompetence) and I’m just not seeing how I could ever convince myself that I could survive being a parent (even though if I were to attempt to be objective, I’m fairly confident I’d be a good one)
