I've been picking for years. Any advice?

I'm a teenage girl, and I've been plucking my eyelashes from my top lid since I was 11. I don't know how or why I started, but I know that it's been causing my eye irritation, and also damages my perception of myself because I wish I had beautiful, full lashes. I do notice that I pick them when I"m very stressed, and usually only when I'm at home. But I can't tell you how many times a day or week I do. The longest I've gone without picking is two weeks.
Any advice to help me stop? I don't want to permanently damage my growth there.
