Well, it's good you got the wakeup call now, instead of when it's too late to repair your GPA. With straight As, your GPA could be up to 3.5 in a year. By the time you'd be ready to apply, you'd be at a competitive level if you keep working hard.
Being in a club won't help much, unless you get a leadership position. Keep voluunteering. Consider seeking a research experience eventually. But don't be distracted by partying and extracurriculars when your priority needs to be a high GPA. A steep upward trend will look good on your record.
Consider your dreams unshattered.
