Right now this is not about getting a date. This is about feeling inferior to my brother. I just feel threatened knowing he has this natural ability to attract girls while I don't. It makes me feel like I am being overshadowed. Also a lot of it probably has to do with trauma I suffered in high school because of him making me feel inferior and rubbing my nose in it. He has changed now and doesn't behave the way he used to, but the damage is done and the scars are still there. I think it is possible that deep down underlying all this is a fear that I will fall for a girl and she will prefer my brother over me. I think that subconsciously I know this is a very real possibility and that if it happened it would be too much for me to handle. Because of this, I feel a strong need to make sure I am on equal footing with him, that everything he has I can somehow match. Now I feel I either need to either convince myself that his witty charismatic personality is not that appealing to girls or I need to somehow develop the same witty charismatic personality myself.

Yeah you probably think I am petty and jealous, but it is the way I am and I can't help it. So you need to try to not be judgemental.
