have to get an IUD

so i just got a new dr and she told me the only safe bc for me, bc of other heath issues is an IUD and i have to come off of the patch i’m on rn immediately, i’m 19 and have used the pill for 3 years and the patch for the last year or so... i’m kind of terrified of the IUD bc my friend had an absolute horror story when she got hers put in. just wondering if it’s that bad every time or depends on the person?
