How do I get my ears to stretch to a 0g?

I've been a 2g for a little over two months. I figured that's a safe time to wait before going to a 0g since I know it's a big jump. I did everything I usually do. I lubed up the taper and the 0g physically wouldn't go in. It had some pain when I tried to push it in as well. Stretching usually hurts a lot for me and yes, I'm doing it correctly. I've waited two to three months between every stretch and there still is a great deal of pain. My ears are very sensitive and I've talked to a piercer about this. He told me that's just the way my body is. My question is how much longer should I wait before stretching to a 0g? It's really irritating me that my ears won't stretch up. Are there any tricks to help me stretch faster? I'm so desperate right now...Are my ears never going to be a 0g, or.
