There are many reasons why your parents may not have given you what you needed.
But now that you're an adult, it's up to you to become the parent to your inner child that you needed years ago. Whatever your relationship with your parents now, you have to be responsible for your wellbeing. And that takes a willingness to clearly see yourself, them and how you interact.
Responsibility for your wellbeing means that you're honest and accountable to yourself - and they are accountable to themselves as well. Disentangling from past influences can be difficult and time-consuming, but that's how you free yourself from damaging beliefs.
So begin by answering these questions: what do you want to give your inner child? As parent to a fearful and vulnerable child, do you know how to give them what they need?
On this day, December 21, 2020, not only is it the Winter Solstice (in the northern hemisphere), but Jupiter and Saturn are closer to each other than at any time in the previous 400 years. If you read online, there are many discussions of this event with varying timelines. Some are calling it the Christmas Star.
Astrologically, this conjunction begins a transformational shift in consciousness. We've already seen old, abusive structures being exposed and broken up to make way for more compassion and cooperation.
