Stay Home Mom with toddler & expecting

MA
37 weeks & 1 day. Been extremely irritable for the past week & still am. Mainly towards my SO & my almost 2 year old. I hate it & truly believe it's because I'm in my last few weeks now. I hope I don't feel this way once my 2nd child is here. I want to be complete & happy. Not annoyed & irritated. 🙁
