16 year old fecal smearing and bed wetting.

Ok, I took in my friend's 16 year old son (15 at the time) last year during a rough time with their family. I've known him since he was born, his parents were friends of my husband and I in college. His hisotry is very tainted. He was abused sexually, physically and I can probably guess mentally, too. He has a list of mental and behavioral disorders which are usually contained with his daily medication but sometimes he still shows symptoms of his disorders even then. I can name that he has a schizophreniform disorder, a number of mood disorders, anxiety disorders in which he has panic attacks and severe anxiety at times. He suffers from anorexia and on occasion I'd catch him purging. I've also caught hima busing drugs and alcohol. He also has seizures.

He isn't a bad kid, I rarely have problems with him and if I catch him doing something I disagree with, he won't aruge back or yell or anything but I do notice that he throws temper tantrums when he isn't getting his way such as when he doesn't want to eat dinner, when he doesn't want to go to the doctor, ect.

Lately, I've found that his medication isn't helping as well as it used to. I know that he's taking it because I help him with the pills and the injection but the symptoms from his mental and behavioral disorders are returning as well as seizures. This has been happening for the last 3 days.

I've also noticed that he would wet himself at night and sometimes during the day. I talked to him about this, though.

But what I found recently disturbed me.

I came into his room to collect the laundry when I found that it was damp. I later discovered it was urine and he had peed not while he was wearing the clothes, but in the closet and in the hamper. I didn't talk to him about this yet because I'm not sure how to talk about it, honestly but I know it can't go unoticed. Yesterday, I came in to check on him because he was being unusally quiet and I found him sitting by the closet smearing his poop on the wall and fresh urine in the closet. He was very quiet and he didn't fight me when I took him to the bathroom and sat him down to ask him why he was doing it. I didn't yell. He just looked at me with a helpless expression and didn't say anything.

I'm uterrly appaled and I don't know what to do. Why is he starting this new behavior?

Has he had any interaction with his abusers recently to re-trigger childhood traumas?
