I hear voices in my head that command unusual things. Please help.

Hi doctor,

Good day, I would like to seek some help regarding my situation. I hear some voices in my head telling me to do certain things that are unusual. I face some consequences that make me feel exaggerated when I am not able to do so. Even though part of me knows that these consequences are too unreal. I still cannot stop myself from hearing it and I feel extremely guilty when I try to avoid it. This happens for many years but it does not happen in my everyday life. It will not happen for a long time. It comes back suddenly and stays for a while and goes away. Recently after experiencing this, I start to feel nervous and I am trying to look for a company. I will have some episodes where I would really become hot for a short time and then, it will vanish quickly. Due to this, I have a heavy feeling and I need to face consequences due to it. I am uncertain about my actions. There are also some things that I have been having. I do not know how to open up about it. I am a youth. I am not sure whether this is something that I am supposed to be concerned about or it is just a phase. That's all for now. Thank you.
