hearing knocking - delusions, hallucinations ?

why they never listen to me.

I had to turn on the speaker all day long and wear headphones everytime i was in bed.

If i'm not do that, i will have to listen to my neighbours knocking on the wall/floor (like a drumm sound) that will make my heart pounding. sometimes it stays a few seconds sometimes a few minutes but sometimes near an hour.

They not only do that in daylight but sometimes to the extreme like 12 am and 3 am. I can't barely stand if i dont counteract with my radio sound.

This is real. I can prove it if I have a video cam. I even try to move near my families when that happened and they confirmed it's real but all that they told me it was because my neighbour modify/renovate her house.

I had been forced to psychiatric ward because nobody listen to me because when I took actions to deal with them by knocking back the wall (everytime they started knocking), people will call the police and believe them that i'm crazy. they don't want to hear my plea..

I try to explained but they won't listen.

Right now i dont know what to do. my doctor told me I had schizo but I don't had any medical report, brain examinations and they never want to know what my problem was.

I dont have any delusions/ hallucinations/ or hearing voices. I can't prove this to them but can they prove this to me?? This thing makes me paranoia because they never want to solved this weird problem I had.

Now will you believe me? If I can show you the proofs will you believe me?

God send me some help. guide me!
