We can be surrounded by a crowd yet still feel disconnected from them, or feel peaceful only by ourselves. Let's imagine my friend and me sitting alone on a Sunday evening in our respective houses. My friend is reading his favorite book and holding a cup of tea in his other hand. He is calm and focused on it; on the other hand, I am scrolling through my social media account, watching others' summer vacation pictures and feeling disconnected from them. Two different people, two different situations, but one feeling lonely and the other just alone. Once you realize it, all the unanswered confusion becomes clear one by one.

Being alone means it's just you and your thoughts; it also means the number of people present. So the answer is that only one person is present, and that's you. Being alone does not have any emotional attachment in our daily lives. Whether you feel happy or sad depends solely on how you spend your time when you are alone. tbh, being alone makes me happy; I can spend more time on my work or in the shower. We can turn it into an opportunity to think about the problems we are facing in our lives and find solutions to resolve them.
When you are alone, you will feel freedom; no one will disturb you or question what you are doing. It's an ideal opportunity to focus on your work, and the result might surprise you. Many scientists and artists got their breakthroughs when they were alone, and no one was there to interrupt them. Some might think being alone is a curse, but it's not true. Just like rain, some think it is a blessing, and some think it is a disaster.
It might sound funny, but being alone can have some benefits. Being able to hang out with yourself is an amazing skill, and it pays off. While you are alone in your room, you get to know yourself and discover what you actually like, not what others forced you to like. Once you are alone, you become more creative; your best ideas will show up.
Being alone is a situation, but loneliness is a feeling. They are not the same; loneliness is a painful sense you feel when you can't connect with others when you want to. Whether it's a wedding or any other party, if you can't connect with others emotionally, you will feel invisible even if many others are beside you. Even if everything happens right in front of you and you are not involved, you will feel like there is a glass between you and others, where you can see everything but others can't.
