Great people, great place, terrible HR - Virtual Estimator Cox Communications Employee Review

Loved working there. The first and last time I encountered HR was my only issue.  Full background: I switched to a new medication that would save me $122 a month. The medication had a lot of side effects. I also moved to a new position in the company around the same time. On the Friday in question, I was out the entire day. When I came to on Saturday I had panic attacks and migraines the entire day and into Sunday. I think some of this was due to the initial withdrawals from the medication as I stopped taking it. When my boss asked why I was out, I offered no excuse as I did not feel comfortable discussing it with him and wished to cover it with HR. I was terminated before I did so. I contacted HR and explained the situation and that I have a medical note. I informed her that the termination was unlawful. She refused to even look at or take the note from my doctor siting the communication with my manager that I offered no excuse at that time.
