I am also currently pregnant with my third child at 31 weeks. I am also a full time student. I completely understand how overwhelming things can get. I have been going through my own ups and downs in the mood department. There is already stress on your body due to hormone changes. Then thinking about getting everything prepared. My stressor lately has been will we have a good Christmas for my other two this year since we have to budget bills, mortgage, school payment, car payment, baby stuff , and now Christmas presents. We have been picking things up here and there but I think this year will be a little slack compared to last year and that makes me feel bad like we are not where we should be financially. I just remind myself to keep a positive outlook because things could be worse and I have been through worse. I agree with everyone who is saying talk to your husband ad let him know how you are feeling. I let my husband know when my moods are funky and sometimes apologize ahead of time just I case I get to grumpy. I also try not to put to much negativity and stress on him because he is working hard and probably stressing just as bad or worse than I am since he is the only one working currently. I also try to distract myself with fun activities with the kids since the holiday season is rolling around and that helps keep me positive.
