help.... i need career advice

i don't know if i should go into nursing. well, i like to study about health and its

diseases. nursing has flexible hours like weekend only for instance and good pay. I no sure if i like nursing. is it gross? Do other staffs pushy? Is it has a lot of stress? is patients pushy. i hope to get a job that is patient less contact,but i willing to accept what going on with clinicals. i believe nursing is appliable to people. like i could know what to do if my kids get sick, or if my parents has problem i could make the best decison if they can do what. tell me more about nursing. i planning to start 2006, but not sure if nursing is for me. i been to volunteer in hosipital but no help at all. maybe you could tell me more what others health career is good. thanks for the help. sometime i am afraid with that i can't handle the situation like giving shots. i afraid i will make a big mistake, but people told me you will get use to it and have lots of motivation toward myself. is that true? please reply soon. thanks
