hi could anyone help me find the title and artist of a song? I only bits of the lyrics.I know it's a catchy song from the 90s or maybe late 80s. The singer is female.

hey hey! do your own thing [...] don't let them bring you down, don't let them mess around, you can do your own thing [..]

u've got to hold your head up high [..] they're not the friends you need [...] then stab you in the back
