Oh, now I think I understand. You have been misunderstood by people at work.
Are you a teenager? I think you are.
If so, you have just learned a hard lesson about life. There will ALWAYS be people like what you have just experienced. It's not fair. Life is not fair sometimes.
But, you hold you head up high. If you have done nothing wrong, you have nothing to be ashamed of. If you have wronged someone, make it right. You will sleep better!
