Get some help: Visit a podiatrist immediately! having "very bad foot pain" is not normal nor acceptable particularly at age 25! good luck..

Have it evaluated: Your pain could due to trauma (fracture, sprain, arthritis, inflammation), infection, metabolic conditions (gout), poor circulation, musculoskeletal or biomechanical abnormality and different neurologic conditions (neuropathy). A thorough history and physical exam and possibly some laboratory and radiology exams are needed to determine the exact cause. The treatment varies depending on the cause.
