Yeah, I feel your pain.
There is no way anyone can eliminate bullying completely as you yourself mention - nor do I think it to be a worthwhile pursuit.
Some amount of friction is good.
Being weird is definitely going to be a problem - I have a buddy who to this day (almost 30) has trouble relating to people and he ranks it as the number one challenge in his life. His parents could afford to put him in sports but didn't think it was a good idea...
You mention how you guys couldn't afford to put you in a sports club. To that I'd say two things: one is that sports should absolutely be free the same way school is free and two - it's a bummer that your parents had kids and couldn't afford these things.
To bring it full circle - it boils down to the parents so often, doesn't it? If your parents could afford to have you participate in extra-curricular activities that you excel in, so much of this childhood angst would be alleviated.
It breaks my heart to hear the shit my friends have gone through and how incompetent so many parents are. The only silver lining is that hopefully - you'll recognize how to make sure your own kids don't have the same difficulties and as a result - the world's a better place :)
