Do I have depression or anxiety disorder? HELP?

I want to loose weight and I been going to the gym for 1 or 2 hours and I feel really good after
I don't want to eat during the day a lot because I want to loose weight
I get really sad because when I do loose a few pounds of more I gain it back
I eat healthy now for months with no cookies or soda
When I eat I always need a side but the I want to cry because I think I am eating a lot with just hearing two healthy things. I do look at the label
I treat my self with ice cream sometimes and I just want to cry
Do I have depression or anxiety disorder? HELP?
