I've developed a very intense crush on someone I found through social media. We've never spoken, and he doesn't know I exist. I think about him every day, check his profile often, and imagining being with him feels very comforting. I know I'm attached more to the idea of who he might be than to the real person because I don't actually know him, but I genuinely want to know who he is. I understand that my imagination and reality are different. I'm wondering whether this is a normal crush, limerence, or something I should be concerned about
