Honestly, it's ok don't worry. You can try and talk to them when you get the courage, but if not then youre going to be stuck in the situation. I know it's scary and all to tall about a situation, but even so you should do so. You're going to keep stuck on not being able to get to know why they're mad at you so go on. You're a very amazing person, even if it scares you, it's really a yes or no choice and it will influence your future actions
