I don't know how I'm going to get through 6(+) more weeks of this. We just moved to Houston so I'm inbetween jobs (wasn't going to start something new this pregnant), taking care of a toddler, hot as heck, and dealing with constant Braxton-Hicks which are driving me nuts. My husband works long hours, and as much as I love having more time with my DD, I'm exhausted and lonely. I'm not used to SAH, so I don't have a great routine and am having a lot of trouble entertaining her cooped up at home. I know it'd be good for us to get out, but it seems like such a chore at times, especially since her mood is so unpredictable and it's so hot outside, and I feel uncomfortably large. I feel as large as I was at 42 weeks with DD, but I'm having a boy this time and I think the weight it all out front. I can't even wish for the baby to come early because we won't have any help here until about 5 days before the due date (our families live far away and we figured it was likely the baby will be late again after last time). I'm terrified of going into labor before our help arrives. Everyone we are close to in this city works full time and has their own kids and demanding jobs. I know they would be willing to help if we needed them to but I hate asking, and I don't know how it would work with car seats. I'm just irritable and emotional and feeling sorry for myself. I know everything is good overall and will work out, but right now I'm feeling overwhelmed. I guess I just need to take one day at a time.

Re: I feel huge!
I'm somewhat in the same boat... We don't have family in town and our friends are all other working professionals. I'm kind of worried about when DD2 arrives since I'll be home by myself all day without any help while on maternity leave. I found it super lonely when I was off last time, so I can imagine being home now would be similar.
Maybe try a moms group? There's Moms of Preschoolers around here that I've considered looking into. Or we have indoor play places where they're fairly contained, and you don't necessarily be on your feet. One in particular has a nice coffee bar for the moms to socialize at.
Either way, hang in there.
