I didn’t smoke marijuana for one day, and It made me really anxious?

I’ve been smoking weed a lot in the past couple weeks, pretty much every day.. and yesterday I didn’t smoke at all, and I felt weird all day. Like disconnected from reality. Somehow, I viewed the world differently. And that night, i got really anxious and paranoid. I was just laying in my bed, and I felt scared of everything around me.
No, I don’t have a mental illness, I’ve never experienced anything that intense.
I’ve heard smoking pot can cause insanity/schizophrenia, is that true? Maybe I was just used to being chilled out, and I was just sober yesterday? Did I have some kind of withdrawal effect?
Has anybody else had an experience like this?
