Is This a Heart Attack

A large anaconda has me around the waist. Squeezing my back so hard, I scream for release. My husband does not wake because I scream silently. I am socialized and it is three twelve a.m. I am gasping now, is this a heart attack? I try to swing my legs out, forgetting my age. You are old! I chastise myself. I am deep breathing. I cannot take one single step, the pain is excruciating. I lean my head onto the mattress. Can I walk? No. I try different positions. Going lower seems to help. I lower myself to the carpet and crawl to the bathroom. I wonder if I will get there. Is this a heart attack? I have no idea, but it is not taking me quickly enough if it is.
