I am scared for my future

I am 19 Male and I am nearsighted dont know the strength of it but I have started seeing floaters I have seen em since I was a kid but this one or two are different… they are more greyish but one id a dot and one is a rather long line worm that drifts ALOT and everytime it does it changes shape due to movement atm I just cant unsee it and as soon as I turn lighrs on all I can think about is if I can see it I dont know what type it is if its mild moderate or severe but its making me nauseous and worried since I most likely going to get more and I dont know if my brain will be able to filter it out and seeing ppl here have such troubles makes me even more anxious and I dont know what to do

And I am scared to the point were I want to cry I could rlly use some advice about how or if my brain can adapt to this cause I dont know if I am overeating or hyper focused I JUST DONT KNOW and I cant think about getting them removed cause I might risk blindness but also I am not nearly so severe that its an option
