Being (A)Lone(ly)
There is a difference between being lonely and being alone.
Being lonely is that scratching itch for companionship that you cannot scratch alone. It hurts and aches until the only thing filling the emptiness inside is frustration, either with yourself or others. Unfortunately, not every person is a companion and it is all too possible to be surrounded by people you share nothing with or people that just do not see you. You can even be talking to someone, but it's all shallow. It almost scratches the itch, but it's always a few too many inches to the left to really help. Of course, on occasion sometimes this drive to socialize nets you a new friend. You meet someone you otherwise wouldn't and you become friends, and it's good. Being lonely isn't fun, but sometimes it's just the push you need to reach out.
Being alone is different. It is true that sometimes there is overlap, sometimes you're alone and lonely, but sometimes you're just alone and that's okay. Being alone is that moment when you can just be regardless of whether that's just existing for a while or maybe lounging in your comfiest clothes (or lack thereof) and doing something you enjoy. Something that may be silly or strange, but it doesn't matter because there's no one to judge you. It's nice and quiet, and everyone needs a break from society sometimes. Some need it more than others. It can be a little dangerous as being alone can easily lapse into loneliness, but generally it's okay.
