Anyone else ?

I’ve noticed today that I have a serious problem . After I finish a TV show or a movie series I get EXTREMELY sad because it’s over . I mean sad in an unhealthy way. I feel super empty !!! Like the characters are my closest friends and family and I’ve just lost them out of my life forever . Like a small temporary depression. Does this happen to anyone else or do I need therapy or something ??? 😂😂😂😂 I’ve just experienced it again while rewatching the twilight series because they put it on Netflix .
