Drunk driver hit my car while I was in bed sleeping. Its totaled. I already got money from my claim but missed three weeks of work Can I still sue?

Assuming that you were paid by your insurance company for the damage to your car, and you were not paid by the insurance company for the drunk driver, you could assert a claim for lost wages if you missed work because you did not have available transportation.  If, however, you were paid by the driver's insurance company, you may have been asked to sign a release which potentially could preclude any additional claims.  Under the facts described, I do not think that you could recover for stress under Pa. law.
