We all have challenges, and it is difficult, sometimes, to understand why things are the way they are, or why people act the way they sometimes do. Life can seem so dark and depressing, and make us feel like there’s no point in trying.
Don’t give up. You matter. Even if nobody believes it, or tells you so. Hang in there, and keep trying. One day, it will all make sense. Probably. Either way, do not give up.
