It is hard to love you if you've been bullied your whole life for being different, having fallen victim to prejudice. My advice, and this is what I'm doing. Focus on your breathing as often has possible, focus on now, not what has been or could be. And most importantly...hug yourself (when, of course, no one else is present). I still have a lot of self-confidence to obtain, but at least I'm still better off.
I have heard that alot of times, the human mind can't tell what is now from memory, which explains why we're so addicted to daydreaming. A lot of memories are very bad, to boot, and come right away, which is why many of us don't love and respect ourselves as often as necessary, because we're addicted to feeling bad. So learn to be more outside of your head, then it will get easier to distinguish the difference between reality and imagination. You deserve to be happy, instead of down on yourself from bad memories.
Here's a relevant poem pertaining to self-love called Love Afer Love by Derek Walcott.
The time will come when, with elation, you will greet yourself arriving at your own door, in your own mirror. And each will smile at the other's welcome and say, Sit here. Eat. You will love again the stranger who was yourself. Give wine. Give bread. Give back your heart to yourself...to the stranger who has loved you all your life, whom you have ignored for another, who knows you by heart. Take down the love letters from the bookshelf, the photographs, the desparate notes, peel your own image from the mirror. Sit. Feast...on your life.
