I had to move back home and now living with my parents and my 2 siblings. Theres always this persistent problem with the 19 yr old brother and my parents have given up on setting the rules with him along time ago. I just wished he would think about the people he brings home and how it affects the people around him. He use this home as though its his bachelor pad and smokes weed as though we don't know what it is. I just want him to think about what he brings home and to keep his business to himself. Him and I had gotten into a huge physical fight just a week ago and the rules after that was I would mind my own business and he won't bring over his ever changing *****s and potheads over anymore. He's suppose to leave all that outside of the home. I don't care what he does just don't bring it around me. Well it was only a few days that my parents wont enforce their own damn rules and he started back up again. I confronted my mom and she just wanted to have a pity party and saying that she's helpless and theres nothing she can do. She's more mad at me because I'm the one making a big deal of everything. I believe that I don't have my parents supports whatsoever. Its a problem with me and my siblings but if my parents doesn't want to deal with the issue then there's nothing I can do.

Please help me with words of wisdom on how to ignore the issue. How do I hold back my feelings? How do I not take things personal and to not resent my parents? I want some peace of mind as I'm handling my own personal issues such as my health but living here everything the tension is so high and damaging.
