jasonjo,
1) your question is poorly posed: anything is "possible".
2) you are overly sensitive: if you think the tiny insults on this forum are abd wait till you get to math grad school. don't be so easily distracted (although a healthy ego is useful in grad school).
3) in an attempt to answer your question, i am hampered by a lack of information. none of the things you mention are either a disqualifier or a qualifier. the main prerequisite is serious smarts and a great work ehtic.
if you have those you can definitely do maths.
point of information: ed witten, who won the fields medal in math a few years ago, majored in history at brandeis as an undergrad. does that answer your question as to what is possible?
BTW: just as anyone is entitled to post any question they like on a public forum, so is anyone entitled to post any answer. so you must learn to ignore the ones that are not helpful and not be led down the garden path of arguing endlessly over who was rudest: a la miss manners.
peace, young person.
