I am 22 years old. Recently, I have noticed that I cannot stop talking to myself. I start conversations and even arguments with people that I create in my mind. I not only talk to them but also get certain mannerisms and facial expressions during the arguments as if it was absolutely a real one. Moreover, I cannot cope with my life and reality as well. I am almost always considering suicide or self-harm and I fear I will do something bad. I feel like screaming really loud and punching everybody and everything. Then, I just want to lie down, listen to music, and put myself in imaginative situations where I am the most excellent and powerful person. Sometimes I wake up at night and the voices in my head wake me up. I feel angry at myself and want to strangle my brain. Please help me.
