I just dont know what to do - pls help?

First thing, sounds like you're nesting and getting ready for the baby. It's natural to want to provide the best environment for your child. My initial instinct is to go with your parents, temporarily, until you can get on your feet and find a better situation, I had to do this, too. I understand there's no room, and your allergies, amongst other issues, but safety and peace of mind comes first. Where you live you can't provide that. Also, your parents/mom can help with the baby which every new mom needs. If it's impossible, can you move closer to your parents? So much going on while you're pregnant, I feel for you. I hope it works out and please email me if wanna chat.
