19 & pregnant

This is my first pregnancy and I am completely lost. I recently found out that I am about 6 weeks pregnant. I barely sleep anymore but when I do it’s nightmares where I’m pregnant and die horribly or have a miscarriage. These dreams hurt deeply. I wake up drenched in sweat, panting heavily, heart pounding out of my chest, and crying.

I’ve been suicidal since I was 6 years old and this baby gave me something to look forward to, a reason to live. I’m terrified. I’m so scared. Why do I keep having dreams like this??
