Period going on for 68 days

My Period is going off for 19 days now and its not like im bleeding super hard, its a normal ammount but ot just wont stop :( im really scared of going to doctors because of anxiety but down there it just hurts since i use tampons and from the constant usage over these past two weeks.. Should i just wait for it to stop or what should i do?

update: period day 28, i went to see a doctor and i got some meds against stress and its probably a hormonal disfunction idk but i hope the meds will work.. :)

update of update: currently on day 68, medication didnt work, went to several doctors and they basically told me that im fat and that i should just wait because im a 'lazy teenager' :*
