I tried to hang myself about 1 month ago. I tied the rope very tightly around my neck that I almost couldn't breathe and I was standing on my toes, I was about to jump. I was choking for quite long time, my heart was beating insanely fast. But I didn't jump. Since then I have black bags under my eyes. Also 2 weeks ago my body began to get very cold, especially limbs, also one night I noticed that my stomach was ice cold, even my stomach, I have lost a big amount of weight and I started to feel big pressure in my head also flutting in my head and neck, even my face hurts. I notice that artery in my neck is very visibly pumping and my heart rate is fast. Could I have damage my neck vessels or is it just my organism coping with stress?
