please help me. I'm begging.

So today while I was at cosmetology school, I had this major panic attack. I literally thought my life was going to end at that moment, I take Buspirone medication for it, and I feel like it making me go crazy. I'm having thoughts about death. I feel like today god is going to take me away, for no reasons either. I feel like my medication is making me think these crazy thoughts. I've never had this bad feeling or anything. Has someone ever had crazy feelings while taking any kind of anti anxiety?
