PLEASE OH PLEASE ANSWER: ugg boots?

Ok, so I have a pair of UGG boots, now i know there made out of sheepskin AND leather. I'm a HUGE animal welfare activists. and fur is one of my biggest issues. I LOVE the boots, there comforatable, and warm, and are good in the winter. BUT, everytime I put them on or think about them, I feel bad, i really want the boots, but i feel like im just like any other fur wearers. I DON'T want them, but I do too. Please, I don't need you to make me feel any worse, it's terrible! I'm a vegetarian, so I think "Well, the animals I save by not eating meat, make up for the animals I killed for the boots" I know that sounds bad. AHH! I'm have a very rough time. Please state your opinion.
