That was helpful actually, I'm going to try to fix my issue about being anxious and over studying hopefully I can see some results ...I'm not sure where to start and I really don't want to go to a therapist or anything.
What falls into the category of "or anything" that you don't want to do? It sounds like maybe you should consider going to medical school as one of those things.
Medical schools and boards realize that physicians are human. They can be very forgiving of problems, weaknesses, and mistakes when you make the appropriate efforts to fix them within a reasonable amount of time. You can acknowledge to an adcom that you were unable to properly manage stress, anxiety, work, and personal life in your sophomore year, and it will in many cases be forgiven if you can follow it up with insightful discussion and evidence that you took the proper steps to remedy your problem.
What will not fly: having a problem and refusing to take steps to fix It or utilize the multitude of resources available at undergraduate institutions. Students and physicians who defer getting help when they need it (whether for social stress or medical illness) have a difficult time succeeding. In particular, those with poor coping skills and who don't avail themselves of assistance, as you will be reminded several times in medical school, account for the elevated rate of substance abuse and suicide among physicians. Now, you may not be in that dire of a situation emotionally, but you don't even want an adcom to question whether your at increased risk of becoming that person (that's exactly why you see so many "tell us about a challenge" secondary prompts and the high premium placed on extracurriculars as outlets).
If you're as anxious as you've implied, and you do not curb the problem, it will likely be reflected in your letters of recommendation, your MCAT score, your personal statement, and any interviews you receive. If going to a mental health professional is ultimately what you need to "fix" yourself, all of those aspects of your application (let alone your quality of life!) will benefit. If that is what you need but will never go, that might trump your GPA or C's as the factor that prevents admission. If you don't need those services at all, they will be happy to refer you to other resources (yoga/meditation groups, academic/learning advisers, occupational therapy), and you will lose nothing for having gone. This is a problem you had to have realized existed before you posted on SDN -- you knew your anxiety level was impairing your functioning, and you knew your study schedule wasn't normal -- why in the world would you feel like you could fix it on your own now when you haven't already?
And the wonderful thing is, you can pursue multiple avenues of "fixing" this at the same time. Start going to office hours, using tutors, visiting your school's learning specialist (they are education PhDs and even top medical students go to them to maximize their performance), studying in groups, or using whatever other suggestions you have gotten here. AND explore the deeper anxiety/mood issues that may be contributing to your habits with a quick visit to health services.
