Help...

I’m 27 weeks pregnant. And I love my little girl growing inside me. They said pregnancy is supposed to be the happiest time of your life.. I’m 17 and I couldn’t ask for more support. The room is full, but I still feel lonely. I feel like I’ve got nobody, even though I know it’s not true. It’s just how I feel. I thought that it was because of my brother (he committed suicide November 5 this year.) but it honestly doesn’t bother me anymore.. or at least I don’t think it does. I feel overwhelmed. My stepmom doesn’t allow me to lay down and nap after school so on top of that Im drained. I don’t want my feelings to hurt my baby girl (I heard they feel how we feel) and I do not want her feeling this way. Me and my dad are not really that close.. he left when I was four and came back last year but I’m living with him. Back in June i had a seizure and they told me I have a growth and they would get into further research and testing on it... I got pregnant before we could even start. My moms family thinks it’s just pregnancy symptoms, but do any of y’all black out? I wasn’t too worried until last week. I was left home alone and I broke down. The last thing I remembered was waking up in the kitchen floor and my arms all bloody. I don’t know what I did or if I did it even. I’m scared of myself... I feel like nobody understands. I didn’t tell my dad about my black out. There’s nothing nobody can do about it... should I tell him?

I tried to throw a little background in here, I Hope at least somebody can help. Thank you.
