So that theory you stated that the shrinking hippocampus is likely a result rather than a cause of depression only applies to people who are not depressed (just stressed out). But if you are already depressed, then it is likely that the shrinkage of the hippocampus during depression will cause more depression?

I believe that to be so --esp in memory and learning skills will be sluggish .

[Matt, I can see that this thought is all consuming for you. Im trying the best way I know how to help you understad this reality of depression.

I think if you understand that depressed people brain because of --prolonged stress-- this will cause and becomes difficult in the way the brain is proccessing thoughts.

This is exactly why depressed people have a repeat pattern of negative thinking. These thoughts make it a harder for depressed people to see more of a postive outcome.

I hope you can sort thru this thought to a better outcome by using the tools --by complying to take meds , get physcial and mental activity,ck cortisol levels etc--- all the other thing we previously talked about.

I understand your reality-- when you said this thought is obsessive to you-- but there is more then depression that shrinks the brain and thats a fact!!

Just would really like you to try your best to overcome this thought. Best Wishes Always!!
