Everyone is constantly bombarded with the need to always be with someone. This is not true. Being alone is okay too. We live in a world where if we're seen alone at the movies, at the mall, out to dinner, and more then it's wrong. No.. it is not wrong. It isn't wrong if you aren't constantly texting or snap chatting someone and it isn't wrong if you walk to class by yourself or enjoy some "me" time.
Being alone allows yourself to get a better understanding of who you are. After constantly being with and around people all day, it could get exhausting. So take a step back and enjoy some alone time. Take a walk by yourself, go shopping, treat yourself, have dinner alone. If people look at you weird, who cares. Being alone is vital for mental stability. Being able to have time for yourself and spending time listening to your thoughts is what everyone needs sometimes.
Just remember that it is okay to be alone, you don't always need to be with someone especially living in a society where you're mocked for being alone.
