Answer
Jacob,
This sounds like a charging problem.  You should have your alternator checked.  If your alternator is not charging the battery properly, that can cause your battery to go bad very quickly.  If this is the case, you will need to replace your alternator and your battery again.  So have both items inspected by a mechanic.
Good luck!
