Wherever you are, be there totally. If you find your here and now intolerable and it makes you unhappy, you have three options: remove yourself from the situation, change it, or accept it totally. If you want to take responsibility for your life, you must choose one of those three options, and you must choose now. Then accept the consequences.
To complain is always nonacceptance of what is. It invariably carries an unconscious negative charge. When you complain, you make yourself into a victim. When you speak out, you are in your power. So change the situation by taking action or by speaking out if necessary or possible; leave the situation or accept it. All else is madness.
The answer is, who you are cannot be defined through thinking or mental labels or definitions, because it's beyond that. It is the very sense of being, or presence, that is there when you become conscious of the present moment. In essence, you and what we call the present moment are, at the deepest level, one.
