Reconciling Sartre's radical freedom with social structures and biology

[Layla37]

I'm an undergraduate philosophy student who has just finished reading Sartre's "Being and Nothingness," and while I grasp the core concepts intellectually, I'm struggling to reconcile the idea of radical freedom and personal responsibility with the very real societal structures and limitations that shape our lives. It feels like there's a tension between creating your own meaning and the undeniable influence of economic class, cultural background, and even biology on our choices and identities. For those more studied in existentialism, how do contemporary philosophers address this apparent contradiction between absolute freedom and determinism? Are there specific texts or thinkers that bridge existentialist thought with more modern critical theory to provide a more nuanced framework for understanding agency in the 21st century?
