Damn im getting too old to party

I went out bar hopping with friends and i got my ass kicked. I feel like trash. I drank too much whicu is nothing compared to what I could do when i was younger. Ive been up for 22 hours which probably doesn't help. Drinkijg gives me bad anxiety attacks anymore so now im shivering in bed convinced im dying. My body temp plummets when i get bad anxiety so yah im really shivering
