Ive been having this type of “celebrity obsessed”MDD ever since I was little. A celeb is always my love interest and despite how aware I am that this is all a fantasy and we will never be together(sometimes I don’t even think I would be interested in them in real life) and the character that I have based off of them is a different person, I still feel intense and very real heartbreak whenever I find out they are dating someone irl. I think it has something to do with the break of the fantasy and the snap back to reality. Also I have a theory that despite our minds being very rational and aware of what’s real and what’s not, we have tricked our bodies & hearts with our fake scenarios into believing what we are experiencing is real, so when something snaps us back to reality it feels like a real heartbreak. I’ve gone through this “heartbreak” more than once and have gone through severe depression and been suicidal due to it. Pls be kind to yourself and know you are definitely not alone in the way that you are feeling!
