I am not much into physics and this is just a guess but I think there is something to it. Sometimes we are in a situation in life where all we can do is get ourselves out of a mess on our own. Surely there are always options of support.
If we had support in the form of somebody believing in us or generally emotionally supporting us it gets relatively easy to move on. But what for the situations when there is no such support and in fact emotional neglect as in dysfunctional families which increases a depressive state. My guess is that It may appear as if we have to do it on our own but I think we do have another form of energy as our fuel. You could name it reverse support.
And I think that it is equal to the energy of support. It just needs to be worked with cause otherwise it has a negative effect by causing low belief in oneself and such things. So one would remind oneself of the situations of negative support and then transfer the energy to something like anger.
My overall point is that it can be discouraging to think one would have to do things on your own but the insight that the energy is pretty much the same, even though it takes a different form and different emotions, may help to use this energy properly.
I also think that it is not just anger but also will lead to selflove and selfcare and most importantly to overcome an undermined selfimage. Again I think the main reason for depression in such situations stems from the perception of being lost and having to do things by yourself especially if you compare to other people who may have more support.
So physically the energy of support equals the energy of neglect and where there is energy from outside there is support from outside, just in a different and surely not in straight forward way. I don’t mean to say it was equally easy but there seems to be a way to use that other form of energy as a fuel and overcome the feeling of no support and by that reach a point where you can easier connect to getting support. Accepting the situation seems to be the hardest part but I think there is a lot of light in these circumstances.
Another thing that makes things harder is when the effects of undermining, feeling unloved manifested in our lives in whatever way and by focussing on that it creates a circle. It is a thin line between not ignoring your feelings and protecting yourself from getting sucked up by it.
