At a loss

How do you know if your 5 year old is lonely or just bored? Judd has been saying that he's lonely. And sometimes sad. The first time he said that word to me...it just broke my heart. I ask him what makes him lonely. He says 'I only have 3 friends at school. The others kids don't like me.' I told him that sometimes having 'only' three friends is okay. That just means that they are good friends. His buddy Holton came over last night for a few hours. When he left, he said he was lonely. Are we not doing everything we need for him? Should I stop doing housework and play with him? Or is this just a phase? A lot has happened in the past 4 months. We moved to a new house, 30 min. from the kids he has grown up with. He has started a new school. He doesn't get to see his 'old' friends that often. It's hard. By the time he gets home from school, it's 4p or after. We can't really go play with his 'old' friends because we have dinner and homework. It takes 30 min to get there. You can say that isn't that far, but trust me he would fall asleep. I don't know if it's all the changes he's gone through in the past 4 months or if its more. Tonight, he said that his mommy and daddy were boring! But in the next sentence he says he wants to spend time with us. That he misses us. Judd is such a sensitive little boy. He gets his feelings hurt very easily. When he says this stuff to us...'I'm lonely or I'm sad', I don't know what to do. I had him call his friend Autumn tonight. We are still waiting for her to call back. I also know that he desperately wants his 2 'best' friends from our old town to come visit. I don't know if they will happen. I'm at a loss. Is it the weather? Is it all the changes? What can I do to make him happy? I don't like seeing my precious little boy sad. I'm at a loss. Prayers are much needed
