Confused

I have been treated disgracefully by the workhouse system. They wouldn't listen to me last time, and they wouldn't listen to me this time. One of my mental health people says he is really angry about my treatment. He says he will help me write a complaint, and organise a meeting with the people, which he will attend to advocate on my behalf. I don't feel at all comfortable about it. I really have a problem with complaining. I find it almost impossible to make a complaint. I know I moan about things when I'm on my own, but that's not the same thing.
