I Am Going Through A Bad Divorce Where My Husband

I am going through a bad divorce where my husband was abusive and left me with nothing. Not even kids and I'm 38yrs old. I'm extremely depressed and stressed. However, from time to time I feel like mu body is burning but is cool to the touch. Last night it felt like my brain an body is on fire. I don't know if what is going on in my life is related, but I'm concerned. It feels terrible.
