Abandonment
One of the most horrible feelings in the world is the sensation of abandonment.
This word is, in many occasions, not well understood.. there are many kinds of abandonment. Your family, your couple, society, friends or even from your work. Problems on any of these fields should be properly well up so we won't feel the most miserable person on earth.
For example, when there is no father or mother around you, or if you don't have any brothers. The presence of both yours parents is absolutely necessary, not having neither of them becomes a sad thing. Same thing with your spouse or couple. If there is no physical or spiritual relation, it becomes absolutely dangerous. A wise solution must be found.
It equally happens in your relation with society and your job. To think that everybody hates you and that nobody loves you, is a sense of guilt whit will be of no use to you. You better talk to yourself and ask, What's wrong with me?
To talk about all this is not so easy, you must go deep into your problems. I truly advice you to learn to live with yourself in peace, to look for happiness inside yourself. First of all, care for you without being too much of an egoist. Learn to enjoy your own company, be happy without having to rely on others.
Be your best friend and enjoy life your own way, what makes you happy without hurting anybody else? Build your own world and do not carry on your back all the misfortunes of all humanity. The human race was born stupid and stupid they will die, of course there are exceptions, you must look for them. I am not advising you to go into a cave and live there the rest of your life, just do not waste your time because you won't get it back.
Love life and enjoy it in spite of anything.
