You might think others can abandon you but that is not true. Only you can do that.
You abandon yourself when you put your attention on the other and believe that this other can give you things you can not give yourself. You abandon yourself when you cry and get depressed because the other is not present... but you are present and you are neglecting yourself as if you were not important.
You give the other power over you by doing this.
Others can not abandon you! Only you can do it! Love yourself ;)
With love and blessings to you all :)
