Should Christians be affected by depression?

I heard a preacher saying depression is not for Christians? how would you explain this to people who were diagnosed as clinically depressed?

Anyone can be affected by depression no matter who you are and what you believe in. It strikes to anyone.

We all have our bad days, I have been there recently. What matters is we trust the Lord’s plans for us. Never forget to pray to God most especially when you feel depressed. He will help us and guide us.
