I should probably seek help?

I'm currently 9 weeks pregnant and I struggle with depression. It's been on and off for about 6 years. I've gotten to the point where I just don't want to talk to my friends or go out. Getting out of bed is a struggle and my boyfriend doesn't know how to comfort me so I just deal alone. I'm constantly crying myself to sleep. I just keep trying to figure out when was a time where I was Happy? It's like I've never been happy and I know this isn't healthy for the baby, but the emotions are so intense and I feel like I fell back into that hole again. Where I just feel comfortable watching t.v. and not doing anything with my life but I want to do something and be somebody. I'm just struggling.
