So is depression a chemical imbalance in the brain or is it brought on by stress??

[AliciaMum]

I really want to know because I have heard so many people saying there are very different reasons why a person suffers depression, i.e. brought on by stress, chemical imbalance, genetic - maybe its all 3 is it??

My Father, sister and myself suffer with it I also think mum does but she is ignorant to the fact.

Both. Well, all 3.

It is a chemical imbalance but often runs in families and can be triggered by stress.
