I doubt that you got pregnant intentionally, just tells me you didn't learn much from your first time around.
Honestly, I don't care whether or not you think it's a good idea. Based off what you've said, unless something has changed, you're living with your mother still? Still working a dead end job, and have a problem with changing your own child's diapers?
No congratulations from me, but good luck with whatever you decide to do.
