For about 3 years now, I've been experiencing unrequited love toward this girl. Normally, unrequited love hasn't had much of an effect on me other than bringing me down whenever I saw her. Unfortunately, it's progressed recently. I purposefully walk out on friends and family that are with their significant others, I get angry every time someone brings it up, I quit my job to spend my days in my room, refusing to come out, and I've lost hours of sleep over it. It's gotten to the point where my ability to function in society has taken a nose dive. I guess what I'm trying to say is, how would one go about getting better? (And no, simply "finding someone else to like" won't work; I've tried it for years now.)
