Your beginning subject title "How do i accept being alone my whole life?" makes me think; "why do you want to be alone?" Isn't the main part of happiness in your life is to find someone to be with? Your confident level is at 'rock bottom,'
In your list, you mention you're 'weird and odd'. Are you the type who enjoys stomping on baby chicks? Hanging cats by their tails from trees? Throwing live hamsters in the microwave? That part really need some explaining!
If you are doing any of the above, then my friend, the only thing you'll need to worry about is, how much time you'll spend in a 'Rubber Room.'
