What do you mean he won't have a problem with it? It's clinical depression. He's going to have some problems if he's not being treated or if the treatments aren't working.
I've been dealing with depression probably since I was about 10 or 11. It can be tough, but it's never hopeless. You can greatly improve with help from others and the right treatment. Are you getting any type of help for your depression?
I don't know what to say...
