Will I be eligible for receiving spousal support if I am the one who files for divorce before my husband?

If I'm the one who files first, I'm worried that it will affect the amount of spousal support & possibly child support payments. My husband makes great money & when e got married, we both agreed that once we began having children, that I'd quit working & stay home with them. We have one daughter that's now 5 years old. She is my everything & I want to be there for her every step of the way throughout her life everyday& protect her as much as I possibly can. I am truly desperate for advice about this because I am not working & haven't for years. Everything we have is under my husbands name, so I feel like I have nothing. No money & having to completely start over with empty pockets & with my 5 year old daughter. Does it matter if I file first? If I file first, does it affect spousal/child support?
