I'm very unhappy. I know this may sound silly to some but I miss my teenage son when he goes to stay at his grandparents house once a week. It's only one night a week but I miss him terribly. I try to find things to do to distract myself and pass away the time but I still miss his presence. It's crippling. I love him so much and I know it's daft but I just want him here. I don't sleep much whilst he is gone, I feel like I'm pining for him. I don't tell him how I feel because I don't want him to feel guilty for visiting his grandparents. Any idea how I can get over this?
