Can my parents claim me as a dependent and I still have an HSA?

I lived with my parents for the first 6 months of the year (they paid for my health insurance provided by the college I went to), then moved out and started a new job and took insurance that gave me a HSA. My parents are claiming me as a dependent. I have contributed money every month from my paycheck to the HSA as a part of this plan, but upon researching it more, it seems that there is a conflict between having a HSA and being a dependent. What should I do/how should I file?
