Relax - enjoy the horn - don't worry about what others expect or think that you should be able to do. I spent way too much time when I was younger worrying about what other people would think and trying to meet their expectations (or what I imagined where their expectations). You can't please everyone, so please yourself as far as what you do with your music. Perform as much as you can, and in a variety of settings. Play solos - play duets - play in the marching band - play in a concert band - try some jazz - play in a brass quintet - don't restrict yourself to playing just one style or type of music. The more you expand your horizons the more you will grow as a musician. Get into an ensemble (or sit in with one) that has better players and learn from them. Listen to a lot of trumpet music, decide who you want to sound like, and work to emulate their sound. Strive to be a little bit better each day as a player - making incremental improvement. Don't feel like you need to become a superstar overnight. No one else ever has) I have been playing since the fifth grade which was in 1959, and I am still learning new things about music. I am writing this in spurts while resting during my daily trumpet practice. Never be afraid to make a mistake. Everyone that has ever played a horn has gacked on a note.
