You are going about this totally wrong.
When you try and attract a member of the opposite sex, you need to present a certain side of yourself. This doesn't mean you have to lie, but it does mean to extents you have to blag those attractive qualities, or more accurately remove any negativity that is holding you back so you can present those qualities in their best light.
I worry and get sad about things on occasion. That doesn't mean I would ever want to tell a girl I was interested in those things, or even my geeky hobbies at first instance as they might detract from other aspects of my personality. Don't you know I'm a handsome, charismatic, fun and outgoing guy?
Sort out your attitude or you will get nowhere.
