Severe gas/Diarrhea/Constipation

Over the past few months I've had constipation frequently. Fortunately, bowel movement always resumed within 1-2 weeks. Recently, I got constipated once again. Through the past three weeks I've been constipated. Sometimes I would get some bowel movement, but then I would be constipated once more within a day. This went on until the middle of last week. That was when I began to get diarrhea. I got the urge to use the restroom often during the school day but was often forced to simply ignore because we are busy in all my classes getting school work turned in and studying for exams, so I went to the bathroom when I got home. On Saturday (yesterday) my diarrhea began to turn from typical to very watery. It also burned quite a bit as I used the restroom. Coloration, however remained dark. I would say that I used the restroom about once every thirty minutes to an hour and was not comfortable getting too far away from the toilet seat. Also it should be noted that after every bathroom run I still felt as if I needed to use the restroom but couldn't, almost as if there was some type of blockage or still some constipation. Today I continued to follow this pattern however the coloration of my stool liquid lightened significantly, from a dark color almost to a tan. Also I noticed that it wasn't nearly as acidic. In addition to this I suffered from severe gas all day. Even now my abdomen continues to rumble. At one point during the day I could not release the pressure building up in my abdomen and I had sharp gas pains in my abdomen. I struggled to pass gas and could even feel the gas bubble sliding down and then moving back up as I applied and released preassure. Also just a side note, I did not use the restroom nearly as often today, maybe only five or six times. I am bewildered by this entire occurrence and  really don't know what to think. Please enlighten me.

Sorry forgot to mention, I'm fifteen, overweight, workout occasionally, and am trying to eat healthier and smaller portions.

Welcome to the gastroenterology community!  I would recommend seeing a doctor about this, specifically a gastroenterologist.  Also, try increasing your fiber intake, water intake, fruit and vegetable intake, and try getting more exercise.  Good luck.
