Parasocial relationships

This is a bit embarrassing to admit, but I believe ive fallen victim to being a bit parasocial. Ive invested alot of time and support into something I really cared about. I recommend it to everybody, and it has saved me through the darkest times in my life. Come to find out they arent who I thought they were, and im having alot of trouble coping with this. It sounds ridiculous, but now I feel as if ive lost apart of myself and my identity...I feel broken. How do I move on from this?
