mood swings Vs bipolar?

[John Amos]

hi am just wondering what are the difference between being bipolar and having mood swings, I think am bipolar because one second ill be normal then the next ill be very depressed then sometimes ill be wanting to do something like go outside or anything really then next thing i know it i just want to be left alone by myself and then ill be calm then all start feeling like if am being rushed. Am just wondering if these are just mood swings or can be something more. thanks
