Bipolar depression

I have had bipolar depression now for three years and my boyfriend thinks it's all in my head but it's not. I'm literally crying so hard right now AMD him and I had a little arguement more than an hour ago and he came into the room and didn't even care like wtf really cuz I upset you but he won't take the time of day to actually have a conversation with me or take me and the kids out for more than 10 minutes. He works graveyard I understand but make time for your fucking family. I'm so upset and I feel stuck I just want to be happy and I cant. And my 5 year old keeps asking me why I'm crying while my 2 year is sleeping. The only reason why im still here is because of my kids. And it seems lately I'm not doing anything right. I'm just so damn tired or making my kids happy make sure the house is clean and taking care if everyone and everything but myselft and I just him to take care of me for once but that's to much to ask apparantly. My bad he works 12+hours a night.
