If depression is caused by chemical imbalances in the brain, how can having bad things happen to you cause it?

I often hear about external things causing depression, but I always thought that depression was caused by exclusively internal things and separate from anything that’s actually happening in your life.

On a separate note, how can things like exercise and therapy help with it?

Bad things make for bad chemicals, and a long streak of severely bad things can make for a lot of bad chemicals. Some people can cope with a lot of bad stuff happening (it’s called psychological resilience), while for some other people the limit after which they’ll spiral into depression is lower. Exercise and therapy are supposed to help with making good chemicals to restore the balance.
