After 7 years of daily use i just panic now

So I'm freshly 18 and I've been smoking weed since I was like 11. I've been a very consistent and very heavy user for the last 3 years since I got my first job and could buy my own qps. Recently tho I've noticed everytime I smoke I just get really anxious I don't get high it's not greening out and I know the weed is good because it got me high as fuck just last week but these last few days it's just panic panic and more panic. Did I fry my endocannabanoid system? Have I just been smoking too long and need a t break? Idk wtf to do and I love smoking weed from the flavor to the feel to the high everything about it just captivates me and I'm infatuated with this magical little plant. I really just wanna get high man😭🙏
