<human>: Give me the gist of the text in a nutshell

Someone I was very close to years ago recently got back in touch with me. Friendship rekindled very quickly but I was disappointed to hear that hes still living in a shitty environment. 

He has a parent who suffers from PTSD and has gone to get help but still treats my friend like a punching bag. I have seen the parent absolutely lose his cool and emotionally assault my friend. Now that he's 19, any type of children's aid is out of the question.

I try to remind my friend that its not his fault and hes not responsible for the abuse. I try to tell him that he doesn't have to make excuses for his parent and that it IS wrong what his parent is doing. I just want to remind him that he is worth something but I don't know if this is the right action to take.

By saying these things am I making it better or worse? My friend is extremely paranoid of his actions, he always wants to be accepted but I want him to know that he doesn't have to try for that to happen. That he's worthwhile and a good person on his own.

Is this the right steps to be taking?
<bot>: Friend has abusive parent. Try to keep things positive and remind friend that they are worthwhile and its not their fault. Try to tell them not to make excuses for their shitty parent. Is this right?
