Opioid Addiction

So I took about 25 ml of hydrocodone yesterday it didn't do much and today I took about 40+ or so ml and for the record I'm 13, I keep slumping forward slowly, sometimes I doze off a bit, and my breathing is slow, I took the medication in the first place to get high and rid of my problems, and I just want to know if I am overdosing or simply took a bit too much. Also everything and everyone looks weird like I don't know how to explain it, though my pupils are tiny, I have some dissociative symptoms I think because of the drugs and I have dissociative symptoms regardless of drugs I'm struggling to stay up writing this, I'm really itchy, can someone reassure me, do I sleep it off or what??
