I can’t poop at his parents house!

Am going to travel and stay at my fiancé parents home for at least 3 months, until we move to our home.

BUT I have a huge problem! I can’t go to toilet !! I can’t poop at his parents home!

Few times I stayed there for 10 days I couldn’t poop! Until I traveled back to my parents home! From

Airport directly to toilet!

When I was at their home, he got me pills ! I was having pain that am not going to toilet! Also pills didn’t work coz mentally ( it’s not my home )

Help me please!
