To love something that you hate, you need to first change your attitude and perception towards it. Have a plan of action that you are going to take in order for you to achieve this change. Give yourself some time and you will be able to love it gradually.
I really don't think that is possible. The only way I can think of is to let time run its course, and eventually one might see that what one once despised, might not even be worth the time even thinking about much less hating or at best, seeing that what one once despised is capable of bringing pleasures once unimaginable.
