Some of the things mentioned here make me wonder about antenatal depression - maybe it's worth a google?
I agree, some of the phrases and thoughts you have used or are feeling sound more like depression. I have had this on and off for ten years. This second pregnancy I am struggling with it a little as I can't go back on my anti depressants due to not enough research on fetal damage. One thing that works for me is getting out of the house, maybe a nice walk with the little one, visiting a friend for a cuppa, getting into a new hobbie like um scrapbooking or cross stitch? Anything to get your mind of feeling guilty and depressed.

I've been working alot more (now that my m/s has calmed down) as being in the house tends to make it worse as you can start associating the house with negative thoughts creating a vicious circle. I'm about to look into swimming classes for pregnant women to get me out there enjoying things, and being more social which also helps take your mind off things

I hope you feel a little better soon! And I'm sure it will pass once your hormones balance out, if not I'd definetly head of to the docs and have a chat about how your feeling. *huggies*
