Can't find my way home

I'm on the train on my way home to Copenhagen. I have just entered the last hour of a 5,5 hour long train ride. I'm not really tired.. Just bored.
I really don't want to go home to my basement. Living in the basement is fine. I'm just so isolated, and I'm doing it to myself. Because I don't want to be upstairs. I don't like it. I feel cold and uncomfortable. But the deal is... I don't know where I would rather be. No place feels like home. It haunts me every day. The feeling of.. Being misplaced. Not being home. Not even knowing where home is anymore. Just sad. Sick of yourself. Sick of the person I am.
