It was really hard dropping my daughter off at college.. Her and I are thick as thieves.. I cried damn near all the way home (300 miles) I promise it will be ok.Its tough at first. My daughter and I both agreed that she and I would text me daily.. She did and it helped both of us deal with big changes.
That was 4 years ago and 95% of the time we still drop a text a day.
I also had to deal with being the only female in the house... It will work out just give it some time. Treat yourself to something nice
