4 months/ weed paws

I was smoking for 3 years a lot of cartridges, and weed, the first 2 months were hell, dpdr, anxiety, depression, neck tightness, head pressure, fatigue, my question is, is it normal to be anxious for 24/7 since 1 month till now it’s been 4 months, is it normal for the symptoms to not come in waves, even tho the neck tightness is way better. And head pressure is gone.
