If you have never been loved it is difficult to know what love is, and even more so to love yourself.
I must warn you though, for those of us who have never been loved learning how to love yourself and receive love from others is a long journey; one with pitfalls(n.缺陷,陷阱)and dips, just like a journey through a barren, dusty valley. The trick is to dust yourself off(dust oneself off: (作好准备)继续做某事) each time you fall down, and to learn the tools that will aid your survival.
Let me paint you a picture. Self love looks like this. It is basically a colourful place, where you are who you are and you do what you want, not what others expect of you.
You accept yourself with all of your flaws, crevices(n.裂缝), and do-wrongs. You look at yourself in the mirror and you see a beautiful you and you find yourself less and less likely to hear yourself say, Oh man I should… so (substitute your preferred adjective here)fat, lazy, mean, ugly.
Yes. Self love is about self acceptance, and not about self loathing(n.厌恶) or rejection. Keep this sight in front of you as you travel and you will eventually reach this place.
