Instead of permanently being lost in your ego and pain, take the high road as you say. Climb on to the highest point of your consciousness and assess the situation from a more distant neutral place. 

Karma, or energetic debt, is something you can carry with you from incarnation to incarnation. Since karma is energy, it can be repaid and neutralised in a variety of ways, it can take many different forms.

The role of your fellow humans is of great importance. Earth is an energetically dense place and a place of free will. Therefore, connections amongst you all are essential to cocreate your Divine Life Path lessons.

The point of being there on Earth, the point of a challenging situation, is to learn from it and move on to something better, something new, something of a higher frequency.

As your Earth soul progresses and evolves, your Higher Self will make a corresponding movement upwards in the scale of consciousness, as high as the highest energetic level within the Oversoul.

Your Guidance comes from a higher perspective, and it aims to make sure that you fulfil the important tasks, contracts and learn the lessons you came here for.

A Higher Self can be inter-dimensional, but it can also have a main focus in one particular dimension such as the fourth dimension here on Gaia. It can have multiple intergalactic incarnations even interdimensional incarnations.
