Schizophrenia-No hallucinations, but high sound sensitivity

I have no hallucinations. But have very high sound sensitivity which makes me difficult to concentrate. I find it difficult to study or sleep in the presence of vehicle noise (motor noise and honking) and television noise. I use earplugs and have double paned windows in my room.

My stay in a hostel campus was very troublesome. I changed room three times as I was unable to tolerate kitchen noise nearby. I could not concentrate on studies when my roommate was making noise with his friends. I find it difficult to study even in the library when others even whisper a little. I also get distracted easily if someone walks by me when I’m studying seriously, though not sound related. In a silent zone, I am very comfortable and can concentrate well on studies.

I am diagnosed as having schizophrenia (hebephrenic type). But the meds are absolutely not helping me. I am currently on Olanzapine, and my doc is talking about taking me on Clozapine.

Am I treatment resistant or do I not have schizophrenia?

I suggest listening to a relaxing music playlist for sleep with earbuds if you're in a noisy environment. I also sleep much deeper when I take Klonopin .5mg and I don't wake up at all in the night. I use blackout curtains (from Amazon) on my windows to block all light. Blocking all sound is more difficult.
I'm not sure if this is related to your schizophrenia. I think irritability is a symptom.
