Hi there! Congrats on the new home. Exciting...but stressful, I know. Last year we built our home and had to live at my parents for 2 months with our 2 children. I spiraled out of control during this time and a little while thereafter. I had several panic attacks and almost fainted looking on symptoms (was really bad!), once we moved and settled in I got better with some help and things returned to normal.
So hang in there, the new house will become the 'new normal'...it will get better. Best wishes :)
