Within the last two years, my family member (I won't specify their exact relation) has completely changed. They always overused pain killers, but this was something completely different. I still, to this day don't know what drugs they are using to cause them to act this way, it is likely a meth amphetamine of some sort that they mix with large amounts of pain killers. They lost their job, and have completely lost their mind. They have become so psychotic that it has caused quite a bit of angst on our family's relationship. They won't admit that they are doing drugs which is causing them to have this psychotic after effect, and refuse to believe that they are wrong. It's hard to cope with and decide how to proceed and help them when this is the circumstance. Does anyone else have any past experiences like this?
