What’s the reason behind this?
i dunno im frustrated 
Frustration is understandable, given the nature of the illness.
Meds aren’t all sunshine and rainbows, especially antipsychotics.
They can have pretty harsh side effects, something you’ll find discussed frequently on this forum.
But they do serve a purpose, and that’s to help establish some normalcy-- a baseline, if you will-- in one’s life.
I was against meds for about 5 years of this illness, and I will tell you that after agreeing to take them, I feel much better and have greater ease with functioning in society. Yes, I did have side effects, but the pros outweighed the cons in the end.
I recently stopped meds for about a month and a half, and it was not a wise decision on my part. Granted, I did not relapse, but the symptoms intensified greatly.
So I urge you to reconsider stopping your medication, as being med-compliant could lead to you leaving the group home in a timely fashion, and embarking on a fulfilling path in your young life.
I tried being med compliant and even that wont help me getting out 
That’s a good thing that you were med-compliant for a time.
They probably want to make sure you’re in it for the long haul.
Be patient in your progress and be patient with yourself.
I want to feel normal again thats why I quit meds
Understandable.
Ask yourself this:
What was normal for you back then?
If I recall correctly, you said you’ve been dealing with some symptoms since you were really young.
So, again, what is normal for you?
Normal as we once knew it is gone after psychosis. However, there are ways to achieve a new normal-- one that combines experiences from this illness while moving forward in life.
idk if i ever had psychosis
I think my dr misunderstood me
Hmmmmm…
Doctors can be pretty perceptive people.
Surely they don’t just prescribe antipsychotic medication without just cause.
they thought my fears were delusions
maybe it’s my fault I’m medicated now
There’s no blame in this illness, for starters.
But your fears/delusions were irrational, and they were severe enough and affecting your life so much so that antipsychotics were prescribed.
maybe i exaggerated it or smth
The whole crux of this is that having the fear that a loved one wants to do you serious bodily harm is not rational.
Your actions in retrospect were to lock yourself in the bathroom out of fear for your life, if I remember correctly.
That doesn’t sound like exaggeration to me.
I know its not rational
Sure, now you know.
But during that moment, your fears superseded reality.
It seems you’re on the right track in identifying that your fears were not rational. That’s a good thing. Could be that being on meds helped you make that distinction. Tough to say, but I wouldn’t rule it out.
They threaten me with injections
What makes you think you aren’t psychotic now?
It’s not right that they’re using the threat of injections towards you.
In a perfect world, med ingestion should be left to personal preference, and not force.
However, injections are not all bad. They do have their place, and have helped many people on this forum regain some normalcy.
I dont have any odd thoughts or hallucinations.
Yeah and it makes no sense because I’m on an injectable already
