Oh yeah I've been there I can get pretty obsessed sometimes. I don't think it's just a manic thing. I actually think theres many people who go through this at least one point in their lives. I think part of it is anxiety and panic and wanting to cling on to someone thinking they can rescue me or something. I was unconscious of it for a long time but overtime I've become more aware of it and try to be honest with myself and to someone else when I start obsessing.
