needed to get this off my chest

So I'm an 18 year old  38 weeks along and I'm pretty sure I'm gonna be a single mom also. I don't know how things are gonna work out but my babydaddy doesn't seem to have any interest in the baby and thinking about my future makes me neevous and stress out. I just have the support of my parents but I've been thinking if the decision of keeping the baby was a good idea I don't know if it's just me being hormonal or what but every time I think about what I could've done to prevent this situation I start to break down.
