Is it normal that other moms and pregnant women piss me off so much?

I am 19 weeks pregnant and I thought that talking to other prego's and moms would be comforting and informative...instead it just drives me insane. I don't believe in using pregnancy as an excuse to sit around being a lazy ass and stuffing my face all day long. You only need an extra 300 calories per day, and it seems like by trying to stick to that and manage my diet every other mom or pregnant girl is judging me! I don't ask anyone else about their weight! I'm sorry that so many women gain tons of weight but it is usually their OWN FAULT. Sitting on their ass all day long, using the pregnancy as the excuse for not wanting to exercise at all or do any extra work and acting like they should pig out on junk all day long, then whining about baby weight!!! are you kidding me!!! Then asking me how much I've gained and getting huffy when I say I have only gained about 5 pounds so far, which the dr says is perfect! I just want all these girls to stop projecting their own low self esteem on me!!! My hub's sister (who has a little one of her own) literally looked at me at a family dinner after I had eaten a plate full of food and said "that's really ALL you're going to eat?" her tone of voice was like she was disgusted. Sorry you had a kid over a year ago and gained 80 pounds and haven't lost any of it yet but stop trying to make me eat tons of food all the time UGH. The pregnant girls WHINING about how tired they are/having to pee so much/all the other crap GET OVER IT. I feel like shit 90 percent of the time too but it is nobody else's problem and I doubt anyone really wants to hear us pregos complaining about every symptom, all the time...they are just too nice to tell a prego to shut up. His sister and my own sister have both lectured me about keeping up an exercise routine...uhm I don't think that 30 minutes a day WALKING on my treadmill and a little yoga here and there is hurting me or my baby. Using pregnancy as an excuse for every.single.thing is just plain ridiculous!! Obviously this doesn't apply to complicated or high risk pregnancies, that is totally different and my heart goes out to anyone dealing with that. The rest of us got no excuse to bitch and get fat, then bitch about getting fat.
