overweight and pregnant mommas?

Just want to commiserate with any other mommas who may be feeling depressed throughout their pregnancies because they're overweight and pregnant. 
I'm having an especially hard time because I'm 30 weeks and I don't feel that I am obviously pregnant to strangers...I don't have a beautiful, round bump rather a bump that sits atop my pre-prenancy belly. I think I just look like I carry excess weight in my stomach- 
Can anyone relate? How do you push through the emotions of feeling like you're getting robbed of a joyous pregnancy?
