Obsessing over someone is a symptom of a larger problem: not having a sense of self.
Let this obsession be a wake-up call that you've not developed your identity as you've grown old.
Find an interest, develop it, form relationships that are mutually beneficial, cultivate shared experiences, make more money. In short, get obsessed with your life and fine tuning your experience here in this transient life.
