I think support is more active than comfort or validation (from the recipient’s perspective). Support encourages one to do. Comfort and validation meet one where one is. At least that’s how I see it.

I don’t mind being offered comfort, my problem is I just don’t believe the comforting things people say. Yes, things might be okay, but then again they might not. Who knows? Only thing to do is move forward and do my best. So it’s better for me to hear something like “you can do this” because that’s more like support to me.
