The greatest challenge for our feelings always comes from the interaction with people to whom we are emotionally attached. It is not a coincidence. Let me explain.
When you examine yourSelf, you will find that you have a fundamental conscious need to be ACCEPTED and UNDERSTOOD. Everyone conscious, from plants and bacteria to human beings have this need. It is the essence of Conscious Existence.
Note, that when this basic need is NOT satisfied - it is almost impossible to experience Higher feelings such as Love. We may even say that acceptance and some degree of understanding are actually the NECESSARY CONDITIONS not only for Love to exist, but even to "feel good".
When we are alone, we CAN accept and understand ourSelves. We CAN accept and understand others. We also feel accepted and understood by Nature and the Universe. Therefore we CAN attain sincere feelings of Love in the absence of the feedback from others.
Now imagine that the "foundation" of acceptance and understanding is completely missing. Imagine that other people demonstrate that they NOT accept you, your thoughts and your ideas - they are not even interested. They "have eyes" but they DO NOT even WANT to SEE who you really are. All they are concerned with is "appearances". They want to SEE you smile, but they are not interested to become aware of what THOUGHTS make you happy.
It is difficult to "feel good" isn't it?
Of course, we expect acceptance and understanding from people to whom we are close emotionally. Isn't it natural? When THEY do not accept us, when they do not understand us, when they do not even want to see who we really are - we feel deeply dissappointed and even upset. Our "foundation" for "feeling good" is absent. It is very easy to lose control and leave the annoying company. I used to do it all the time.
Now I try to see them as babies. Can you blame a baby that it hasn't yet learned to walk? All we can do is to SHOW babies how we walk ourselves and offer our assistance when and if they CHOOSE to learn to walk. Of course, it IS still dissappointing if a baby CHOOSES not to try...
The only solution I see at the moment is to keep walking...
