It's said that introverts love to be isolated, I believe that works perfectly for them until their late 20s when They begin to desire companionship and seek to be loved and once they are not getting any, it hurts, making them feel rejected. Before I turned 28, I was comfortable with being alone, I wasn't missing the companionship of a friend, I never bothered but as I grew older, I realized there was a vacuum that needed to be filled, loneliness began to hit, I no longer enjoyed being indoor, I started to want to make friends, but it was difficult communicating with people for someone who had being an introvert for a longtime. Even when I was dying inside, I still acted strong on the outside. I knew my pretence wouldn't take me long before I broke down from the pain the vacuum was creating. I wanted to be strong but it seems at this age, my whole being needed to be loved by someone and not myself.
A wise man once advised his adolescent son to make friends before he turned 20 so that he wouldn't be lonely. I never saw sense in that, but it seems he was speaking from experience, he understood a time would come when being isolated would no longer fascinate us, All we would seek then would be friendship. Loneliness is a disease that eats up a man and leaves one miserable. It makes you feel like you're all alone in this large cosmos fighting every battle all alone. What keeps us going is the smiles, laughter, and memories as friends. Most people who end up in desperation are those who are isolated and with no friends who cheer them up when things go tough. We need friendship and love at every point of our life, loneliness is a disease, and it's cancerous, it spreads to our whole being and makes us feel invaluable and rejected. Make friends while you can, isolated life doesn't profit in the long-term.
Make as many friends as you need. Loneliness kills, it kills your ability to strive on, kills your motivation to keep pushing, and makes you feel unworthy. No one enjoys being alone, even our creator said it's not good for a man to be alone, and a companion was made for him. You need a companion, you need a friend, you need someone you can run to or share your pains with, someone who will make you feel worthy. Loneliness can't do any of these.
