Hey OP.

You may want to check in to lyme disease.

PTSD, chronic fatigue, depression, IBS, chrons diease, MS, cognitive dysfuntion, and all that stuff can often be traced back to low level infections that one's immune system can not clear on it's own.

I put lyme disease as a major culprit for many undiagnosed health issues.

50% of IRAQ dogs have been found to have lyme disease. Sorry for no link, but there was a study that shows that.

Check it out. Recovering is difficult, but can be done if one takes care of their gut and avoids the right foods.

God Bless.
