do i need to seek help

im addicted to hhc (semi synthetic and i do acid every week and i have a craving for ketamine since i did it, every weekend i try to steer clear of the acid but yet i still get the impulse decision to do it ive managed to steer clear of stims due to my addictive personality but now that i tried ket ive got a desire for dissociatives, i havent noticed any signs of hhpd except astigmatism which i cannot recall if i had before my first trip my question is if i should seek help
