I'm going to pretend to be pregnant just to get some sympathy from my family and friends.
Is it because you think people will give you more sympathy knowing that you are pregnant?
Yes, people always treat pregnant woman with sympathy and kindness.
That is so wrong on so many levels. You shouldn't pretend to be pregnant to garner sympathy because people are not stupid and pregnancy has a time duration so you can't keep this lie going forever.
I will pretend to be pregnant and then act like those hormones will give me some mental disorders.
At some point you will be found out.  You should be more honest about needing attention from others and finding a more productive way to do it.
