I am scared of vegetables?

The reason why I am overweight is because i never eat vegetables. The reason for that is because i am scared of them.... I can't stand the look of a carrot or texture of broccoli.. It also doesn't help that my gran sits on the couch all day. For the past year all i have eaten is McDonald's. I now weigh 213kg. I just don't want to be afraid of vegetables. Any suggestions?
