I didn't care much for the tweet, but the topic is obviously important for people who are still living with their parents. Is living with your parents “childhood”, “lame”, “weak”, “pathetic”, “loser-ish”? Nah, those are just definitions. Nevertheless, there is no doubt about it that it's not healthy for you, IF your parents are toxic.
To all 20 somethings who live with their parents: If your parents are toxic, then you must make it a priority to leave as soon as possible. Make it your primary objective and let nothing stop you. If you have to move heaven and earth to do so, then so be it. Remember that toxic parents will attempt to manipulate you into staying. You must nevertheless gather enough willpower to escape from their grasp.
Toxic parents want you around them, but you must nevertheless defy them until you've moved out. The 20 something friends I know who are afraid to defy their parents tend to stay much longer around their parents than they should, yet I consider defying and challenging your parents to be one of the best experiences you can have. When you defy your parents and you keep defying and you make them understand that you're going to do whatever you want, you feel your own power and it makes you more confident and positive in life.
Moving out was the best decision of my life. My parents are immensely toxic in various ways, and while I pretty much never listened to them, it doesn't change the fact that many of the things they did were insane. My life improved immeasurably after I left my country. I now see them once a year tops—it's perfect.
I think people who are still living with their toxic parents have no idea how much it really harms them. It stalls your growth in the material world. I make damn sure whenever I see my parents that I'm well prepared mentally and energetically. I do the same with all toxic people, actually. When I know that I'm going to have to spend some time around toxic people(an extremely rare event these days), I will almost immediately strengthen my resolve to not be influenced even for a moment; I make myself feel indestructible. This works very well.
I appreciate my parents a lot though. I have become very good at keeping my social circle completely clean of unwanted guests and I will instantaneously reject toxic people—and I can detect them very easily.
In a sense, it's a bit sad that so many of us didn't have better parents; But those of us who manage to transcend it and grow beyond our upbringing also tend to become stronger than people who didn't have those challenges. Bit by bit we retake our power and we go out into the world. It usually isn't easy, but it's worth it.
