When you are in trouble do not despair. All your pain is an invitation for you to awaken and to remember. It is ultimately not real, just like your body and your mind. You are neither. What you are is awareness itself . You are That about which it is impossible to say anything. It is beyond the world of words.

 You are That which is aware of pain, aware of every experience. The deeper you learn to be aware of yourself as awareness, the more relaxed and peaceful you will be, until the moment you realize that you yourself are that awareness, only That. You will learn to take your stand in awareness as awareness. You will see, you cannot have pain or depression as awareness. These phenomena are for your body and mind only, these two are illusory. What is illusory? Everything that is impermanent, everything that arises and ceases again, everything that depends on other factors for its existence. This includes all objects, perceptions, thoughts, feelings and all aspects of body and mind. 
 You are safe by definition; it is your characteristic as imperishable, indestructible, eternal, almighty, omnipresent, all-knowing, radiant awareness. Let go of your old identification of yourself as a body, let go of your old knowledge of yourself as a mind.
Let it go and meet the Light that you yourself are. Open yourself to it. Be curious about your own essence, your own nature. When you have learned to see clearly, you will understand - it does not matter at all what you have done in the past as an ignorant energy pattern identified with the person who has body and mind. That was not you, that was just burden of your old conditioning and that is pure ignorance.

I am glad that you are here now.  When you thoroughly examine yourself, you will discover that everything that happens is universal and subject to universal laws and patterns. Nothing is personal. There is no such a thing as a person. All patterns will continue to repeat themselves with ever-changing details until the moment you understand them. Then you can be free from them and let them go. Every pain, physical or mental, is caused by something that is not understood. And what is not understood is held by our system as a potential source of growth for our understanding. You are not a body, not a mind and not a person.  All of these are temporary, impermanent vessels. Relax and rest in this empty, open state. Breathe and let everything be. Just as it is. Until you can let everything go, what means letting go of  your opinions and visions of everything. It wouldn't be you that will make it happen. It will happen on its own.

 This detachment has nothing to do with farewell and loss. Remember,  nothing can be lost.  
There is no question of farewell, there is a question of transformation.  About a hundred years ago, famous physicists made great discoveries. They tell you that you are nothing other than sparkling, free, radiant, subtle, brilliant Intelligence energy, which is awareness or life itself and that everything you experience is of the same nature. Energy cannot be destroyed, it can only be transformed from one type into another.  When you realize that everything that appears is merely different modulations of a single energy of awareness, you'll see that all of this will also dissolve into the same energy. It happens constantly, actually, it's happening right now while you're reading this.

Everything you experience is transient. Everything except yourself, provided you could have recognized yourself as That - as an immeasurable source of consciousness that is alive and peaceful, that gives rise to everything, encompasses, contains, and dissolves everything back into itself. How then can you say you are lonely? You are full, full of yourself. "My silence sings, my emptiness is full,"  says Sri Nisargadatta Maharaj, one of the greatest spiritual teachers ever. Stay here. Nothing more is needed. For there is nothing wrong anymore. You are That. You have arrived.
