Question about guttate psoriasis

So I have had guttate psoriasis since I was 5 years old after getting strep throat a bunch, and I was looking online just to see why that even happens and I read a couple articles that stated that guttate is supposed to clear up in a couple weeks after the infection. However, mine had never gone away (I’m 20) and it hasn’t morphed into plaque psoriasis like some sources say it can since it still appears in the little circle shapes. Anyone know why that is? Am I just a weird case or what?
