You need to start taking yourself seriously. Your upsetness is important, even if (and that’s a big if) the things that are making you upset are stupid or small or pointless. That doesn’t mean, mind you, that the rest of the world is required to do what you want when you’re upset, but absolutely your feelings are valid. Valid valid valid, and sometimes you will be right! But being right isn’t the issue. The issue here is that you need to value yourself enough that even if your concerns feel small to you, the fact that they are your concerns makes it important enough. Your feelings are important to the people who care about you. You being hurt means something, even if the other person didn’t mean to, or you’re being silly, or whatever excuse you tell yourself.
