1. The DO aspect i'd worry much less about your chance of making it there are very good.
2. MD - You do have a chance, but its just that, a chance, many people have been accepted with your stats to medical schools, and many people with your stats have been denied with your stats. Your list of schools is really good for your stats, your applying early is also another plus. Its my belief, that eventually, with your stats, you will get in somewhere eventually (waitlist etc). But you have every right to worry, please dont end your efforts, keep doing things to improve your application as you apply find a way to maybe raise your GPA a little, show an upward trend and be active in activities still incase you end up on a waitlist they see you are doing a lot still.
3. Md schools are all competitive, and its not all a numbers game of course, but a large part is, and if you have either a GPA or MCAT below a schools certain median or average, its tough. Its ok to be nervous, everyone is nervous, you from what i saw in your applicatoin have done everything you could, and thats all you can do. However its good that you arent cocky or arrogant, a sense of being humble will help get you through this process, because even at CLOWN COLLEGE USA with MCAT average 25 and gpa average 2.0, you never know what they are truly looking for, you never know if the interviewer has it in foryou, and you never know if they think you wont attend there in the fall so they just dont accept you.
