26 weeks and the worries kick in

William has been quite active lately. We had a big storm the other night and I think he loved it, because he had never kicked so much, so hard and so all over the place before then.
I love to feel him kick and I'm getting used to his routine. Usually very active in the morning from around 8 - 11am and then again around 3pm. But most other times he's pretty still. Every now and then he'll wake up in the middle of the night when I do to go pee, but he settles pretty quickly. I'm hoping that's a good sign!!
So I'm 26 weeks and I've gained probably 15-17 lbs. Which feels like a ton. I feel gigantic, but honestly I don't feel like I've put on a whole lot of weight in my legs, arms or face. I'm just one big giant belly.
There's a lady at my office who is 2 weeks ahead of me and her belly is much smaller - but her face and extremities are puffier. I know I shouldn't compare, but I wonder if that means I'm having "giant baby".
My mom freaked me out when I told her I had gained 15 lbs cause she acted like that was a lot considering I have 3 months left. I'll admit I'm at the top range of where I should be, but still with in the "healthy weight gain".
Also, my glocuse test is Tuesday and I'm all worried about that. I do not want to fail it. I'm dreading it. That and the fact that I gained 6-8 lbs this month alone has me dreading my next appt.
And the nursery is no where near done. I've sat and looked at a mound of sewing for weeks now thinking "I really need to start on that" and just haven't been able to motivate myself to do it.
And the strangest - or rather most selfish - worry of all:
My feet. They have started to swell I think. Right now only after sitting all day and if I prop them up, they go right back down to normal. But I'm terrified of my feet getting bigger.
I have really adorable tiny feet. (Sorry - but I do) I wear a size 5 1/2. I have a bunch of super cute sandals and pointy toed patent leather 3 in heels in awesome colors like hot pink, red and butter yellow. I love my shoes. I have often found a pair of shoes and then built an entire outfit around them. I know I can't wear them now, but it will make me very sad to find that none of them fit after the baby comes.
