Getting frustrated..

So I'm 31 weeks and lately I'm feeling so overwhelmed, I just want my baby here already. However I worry about being a good mum when she is here, I think I'm just hormonal lately and getting frustrated because I feel so uncomfortable all the time, tired and can't sleep and just a bit yucky! Just really wanted to rant and hope that someone out there was feeling the same. Can't believe I have 9 whole weeks left to go and it's only going to get worse! maybe I'm just being negative and having an off week, who knows!!
