The Introvert Question

When I was younger, I used to ask myself: "Why is my rib hurting?" "Why do I get panic attacks?" "Why is this happening to me?" 4 years later, I still suffer with no questions answered, eventhough I'm starting to force myself to go to theropy. My parents and friends recently started to notice that I've been acting happy for a long time now, and that they made it known that they're sick and tired of me hiding my pain. But I have no friends, those so-called "friends" bully me, don't listen to what I have to say and only treat me kindly when they need something. I realize now that I don't need friends. I don't need anyone. All you need is yourself, and that's what will keep you motivated to move on.
