What Causes Heaviness In Chest Along With Sweating?

I felt like I had a heart attack last night, I took one drank of blush wine and it felt like an elephant was sitting on my chest , I was sweating, my arms hurt, my face was white.... So I hurry and took some anxiety meds I had in my bag and after about 30 mins I felt better..slowly. I didn't know what else to do, I thought I was going to pass out or die! I have aniexity and I take Zoloft for depression. But this have happened to me before I started taking this meds. What could be happening to me? I'm 31 and its so scary!!
