I feel depressed since years

Hello, I am already since years depressed. I am always tired. Don't feel like doing anything. When I am alone I have to fight my tears. I lost my mother when I was very young and now that I have kids it feels like I have nothing to fall back on. As if I am on my own.

My father has a girlfriend, but she is not so good with kids. It often overwhelms her too. She also doesn't want me to visit during the week, only in the weekends. My father has holiday now, but I cannot come before Sunday. This hurts me a lot. It also feels like I cannot talk about it with anybody. My husband knows, but doesn't know what to do with it.
