Does Ritalin make you really emotional? ?

Especially, during finals? I cry, i become indecisive I sleep more. I have been prescribed Ritalin since freshman year of high school and now I'm in freshman year of college meaning I need the medication even more. I went off them for a week. I felt better and more myself but I lost a lot of study time. I don't even know how to use the medication anymore because I stay up all night. Someone please tell me how there experience has been. And please suggest something other than talk to my doctor. Thanks.
