Remember you have MEPs representing you as well. European elections too often play a distant second fiddle to domestic ones but this really should not be the case.
Domestic politicians have the ability to instigate changes to legislation. MEPs lack that power - all they can do is block bad legislation from getting passed.
MEPs sit in the European Parliament, which is a talking shop, with very limited powers. It's hardly surprising that few Europeans know who their MEP is.
