Feeling overwhelmed.

Been lately stressing out and feeling overwhelmed about not having anything yet ready for my baby I'm due on March 4 and the only thing I have is her bed I haven't bought anything else and I'm worry I might not have everything ready for when she arrives with my other two kids I bought everything ahead of time but being my third pregnancy I haven't been too excited about it maybe because is the third should I just wait for my baby shower or start buying things already.
