I keep experiencing pins and needles in my hands, feet and face. it feels like i'm hyperventilating, but i'm breathing normally. i have breathed into a bag to see if it helps, but it did nothing. i took rivitrol to calm myself down, but no effect?

Need to examine: It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor and discuss if you may be depressed. Counter-intuitive as it may seem, exercise may help. Start with low intensity exercise such as walking and gradually increase the intensity as tolerated.
