Yup. I'm fairly certain everyone has that point in their life. All you can do is keep on taking life as it comes and take every opportunity you can to move forward. Things'll get better.
of course human life matters, just lookat the differences one person can make, look at king jr, or julius caesur, or even less important people like game developers, they make so many people happy, by just being themselves
there wont always be another person, sometimes there is only one, sometimes you have to be that person, people like you are theones that keep society going, and you are just as important and needed as everyone else
remeber your meme canon, all the people you will save, the people who adore yu and look up to you, think about them, everything matters, there is no such thing as nhilism
Everyone has doubts about who they are. You can either look inside yourself to try and make yourself a better person, or at least one you accept, or you can accept who you are and try to live an enjoyable life with others who accept you.
yes you are who you are, but that meansyou can be whoever you want, your not a constant but a variable, everything can chanfge if you want, you just need to trust in yourself, and thse around you
