anxiety attacks vs cramps

I've had the worst cramps for the past 2 days. Every night I wake up with pain so bad. Just tonight I woke up and started overthinking it and stared getting an anxiety attack. My muscles started tensing up and I couldn't stop shaking. I kept sweating and got really really nauseous. I am trying to calm down. And I really want this period to end, it's literally being the death of me. I can't take this anymore
