Lonliness is a fact of lilfe. It's not fun, but it happens. We just need to settle into it and learn to be our own best friend. This doesn't mean we forsake other relationships, it means we embrace them as much as possible, but we still nurture our own relationship with ourselves. Loniliness sucks. There's really no other way to put it. But we do have to learn to live with it. When I feel lonely 1) I reach out to the Lord. He is always in you, around you, and near you. Embracing that truth can ease loneliness. 2) Call/text a friend just to say hi. You could tell them you are lonely, but you don't have to. Sometimes its good to know that someone cares that your alive. You don't have to talk for hours. Just say hi, chat about the week, and move on. You will be sad, but sadness never killed anyone. 3) Get moving. Take a walk. Clean. Walk to the nearest 7-11 and get a coffee. Do something to break up the monotony. 4) Pray. Sometimes the loneliness is so overwhelming you have no words. Then just cry. Get mad. God's a big God. He can handle it. Just say "Jesus" over and over again. Prayers have more to do with your heart than the eloquence of your words.
These are all things I do when I'm lonely. But I also plan ahead. I make sure that I'm realtively busy. I am not working, so I hang out at my church. I volunteer. Just get out of yourself.
