I think, it's normal to feel alone even if you are with family or friends. It's normal to somehow feel like you are not supposed to be in a certain place, at a particular moment. To not feel like you have to be with someone. To not feel like you need company, sometimes. But it's not normal when you feel all these, because they make you feel this way. There is nothing wrong with you; you are simply surrounding yourself with the wrong people.
