Depression

I have struggled with depression for many years. I've been on and off medication, and I struggle to be blissfully happy. I'm 25 years old, and lost my dad 5 years ago. My husband didn't step into the picture until a couple of years ago. My entire family recently moved away. My closest sibling lives 5 hours away, another 10 hours, and my mom and other siblings live 15 hours away. I don't know how to be a happy person anymore and I feel bad because I don't have the energy to take care of my husband the way he deserves. He comes home from work and still cooks and cleans. I find myself thinking that if we conceived, it would bring that happiness that I've been looking for.
