I just have studied holistic life coaching mind body connection and we learn a lot about stress and the affects on the body.
Loosing a loved one can have so many stress affects on the body, impact your well being. Way more then we understand sometimes.
It goes way beyond, what medical test can pick up.

Stress can cause some of the biggest gut health issues, until this is sorted its hard to find balance.
As i have been though rebuilding my gut, it doesn't take weeks it took me about a year to really get it back into balance.
I completely under stand, just wanting to feel like you are back to normal again and wonder if its ever going to end.
It does take a lot of effort, working though the emotional state, the physical body, your whole being to bring back good balance. It is so possible to do this.
I remember no one could tell me what was wrong and one day i walked into Robs offie and he was the first person to tell me he knew what was wrong he could help me and i can fix this.
From that day on what he told me to do i done.
So its defiantly possible to get back to good health and along the way you get to learn so much about your own self, it really can be a blessing.
Enjoy doing something nice for your self today. I would love to hear what you do :-)
Please if you need any help or someone to talk to. I am here. :-)
