Need help with flossing

I posted on here before about how I went to the dentist a month ago and they told me I have gingivitis and puffy/inflamed gums and they told me to floss everyday. Well I have been flossing everyday for a month but with using floss “plackers” like the floss picks. People told me to switch to expandable floss which I did and my gums hurts so bad flossing still .. it feels like they ache bad and they bleed . And it will still ache after flossing for like 10 minutes. It feels like someone punched me in the mouth and it makes me not want to floss cause it hurts so bad . I don’t even have cavities or anything but my gums are messed up I guess. Next thing to try I guess is a water pick which many people suggested but I looked it up and some sources say it doesn’t work as well as normal floss so idk what to do. Thinking about making another appointment to the dentist because of my gums.
