Baby girl, God hasn't left you or betrayed you. In times like this, I truly believe he's trying to see if we are willing to leave him or betray him. Lean on him. Trust him.
I have been knee deep in bull crap, not seeing an end to it and thinking of suicide myself. I fell on my knees in the moment I thought would be my last and begged him for ray of light. He showed me the way out. I've trusted him since. My life hasn't been perfect since then, but it's still beautiful.
He has given you the gift of the child you are carrying. He has trusted you with one of his angels because he has faith in you. If being with your husband is bad for you and your baby, get out. Leave that situation. You don't have to go to your parents. There are places out there where you can get help. You have to be strong enough to make a solid choice and stick with it. It won't be easy. You will have struggles. That beautiful life growing inside you will be worth it all. Please get help for your self and your baby. You are both worth it. I promise. There is love out there. People will help you. Talk to your doctor. Talk to your pastor.
You're pregnant...You're gonna have ups and downs no matter what but if you're already talking suicidal then you need to let your Dr know so you can have someone to talk to. I went through it with my first born and didn't get any help til after I had my baby. I'm glad I took the step to get help. I was severely depressed and wanted to end my life. I then realized my baby needs me! Positive people around you will help but negative people will always want to see you fall on your face. The choice is yours...best of luck and God Bless :)
