I Had A Very Trauma Incident Happen To Me That

I had a very trauma incident happen to me that my dog died suddenly while I was walking him one morning. He died of a massive heart attack. My dog was everything to me and we had a very strong bond, he was like a child to me. I have never in the past suffered any type of stomach problems or appetite problems but since the day he passed I have a very poor appetite and nausea. I try to eat as much as I can I am better with supper then breakfast and lunch. I also want to add that I am a very anxious person and i have been on treatment for this for years. The passing of Harley was something that has definitely increased my anxiety especially being such an unexpected death. What area your thoughts on this....will the appetite start to come back the nausea is not there everyday but more yes then no. It has been 2 months since his passing.
