It'll happen man. Just keep improving that application packet, look for little ways to improve its appearance, the content, etc - just little things that help it stand out. Maybe look at ways to improve your interactions at meetups as well if that's a factor. I was feeling exactly the same way, it really sucks until it doesn't. Have you had any interviews or have you been getting shot down before that point?
There's also plenty of folks (including myself) who'd be happy to take a look at your application and give you feedback. I shared mine with a few people who were super helpful.
