I am 6 and a half months pregnant with my first child. Lately Ive been noticing, that I will be fine, happy, normal, the usual, and the tinest, smallest thing aggervates me to no end, or completely pisses me off and I get very angry for anywhere from 15 min to an hr or 2. These things could range from my step kids coming for the weekend and then I find out they are staying for a day or two longer (extreme anger), to having to re-do the wash because my husband threw the clean clothes in with the dirty ones (frustration). I completely shut myself off to almost everyone, so as to not "explode". I dont think this is depression, or bi-polar because they sway from the ups and downs..but Im no doctor. Lately I am completely disgusted with the idea of the stepkids even coming, and with school being out for the summer, they are probably staying longer now than just the weekend...I know unless I fix whats wrong with me, I am going to go crazy and end up saying something to my husband that I'll regret. Whats wrong with me and what can I do to make it stop? I just want to be happy again.
