Sad on Week 33

I don't know how to describe my feeling. I married with my husband who had ex-wife and already had 2 kids. I love his kids as my own and I am pregnant now with my husband. I almost gets there. 33weeks. I don't know how your husband take care you when you pregnant. What i have to deal with is clean up all the time, and make everyone happy includes my husband's ex. I don't see the point of living. Try smiling with life but it is so hard. Want to give up!
