break up 💔

I've been so sick to my stomach since me and my ex broke up that I hate been able to sleep in 2 days, my eyes burn but I'm not tired at all. I've cried and screamed. I even passed out twice from dehydration because of how sick I am to much stomach I can't even keep water down. I don't know what to do anymore I gave him everything I had for the last four years just to walk in on him sleeping with another girl.. please someone help me I don't have many people in my life to talk to, I actually have no one anymore because I was so wrapped up with him I lost contact with all my friends and family. I just need to know how to get past this. We've broken up before and fought pretty bad before but nothing like this. I feel numb but at the same thing everything hurts. I loved him so deeply I forgot about myself now I don't know what to do.Â
