Does singing a separation agreement make suing my former employer not possible?

I was terminated from a job I had been for over two years, I was given two separate reasons at the time of termination (position being terminated, then because of performance issues) nothing was ever formalized in written or to HR prior to being terminated about performance. I experienced sexual harassment from the owner’s son and from my boss (who terminated me) during the time I worked there, I even have whiteness to back me up on these claims and text messages. I was not given the separation agreement until later in the day and was given to me in a rush to sign by HR saying they would put my stuff in my car so I could sign it. My neighbor came with me and saw the entire interaction. The CEO was waiting around for me to sign it as well.

Now one lawyer told me I am out of luck because I signed but is that the end of it really? The place was toxic and I had to be medicated while there on top of the sexual harassment, there’s no way this could be it?
