As the title states I have absolutely no right to be depressed but I am

I’m 34 and married to a beautiful caring wife, I have 2 beautiful girls, loving pets and absolutely no financial worries,

However I can’t seem to shake this feeling, it’s hard to describe but it’s like my life is in a big lull, I wake up in the morning with no energy and it’s hard to find happiness in anything,

I just feel like I have no right to feel like this as people would do anything to be in my position but it doesn’t help!
