You have to love yourself, not thinking about what you deserve love or not. You zhivy- and it is sufficient proof that you deserve love, just as you deserve breathing. You do not ask, you deserve the right to breathe or not. Love is almost invisible food for the soul, just as food is food for the body. And if you are overwhelmed by the love of self, you will be able to love others. But love healthy. Love strong. Take care of the sick, the old. Zabota- is quite another matter.
