The fact that your child has left home does not prevent family problems from arising or continuing. Do your best to refrain from burdening your student with problems from home for which they have no control. Sharing these problems with your student may cause them to worry excessively and even feel guilty that they are away from home and unable to help (however, you likely have the best sense for how your child may react to distant family issues, and will need to proceed accordingly). The college experience changes every student, and it is likely to change your family dynamics as well.
