my boyfriend of 3 years recently moved to another country and we now have a massive time difference between us. i feel anxious all the time now and am unable to concentrate on even the simplest tasks. i am constantly thinking of him to tge point it has become an unhealthy obsession. i carry my phone every where i go and constantly check it for any messages from him. meanwhile, he does not seem to be much affected by this shift and is usually busy. he was very understanding when i told him of my feelings and did try to cheer me up but the happiness slowly dims a few hours after we cut the call. please help me
