I am a person with bpd tendencies (19, currently working on a formal diagnosis with my new therapist) who is starting to see the same beginnings of this disorder in my little brother (12, we have different mothers) that, through therapy, I see in my younger self. Our dad is emotionally distant and struggles with severe PTSD from his own childhood emotional abuse and from being deployed into a war zone twice. He has not gotten better since I was my little brother’s age, but recently reached out for help from the VA. My stepmom has helped him on this path a lot but she herself also struggles with emotional availability sometimes (she’s kind of traditional). I don’t really go home that much, but the last time I did, I gave my little brother my phone number in case he ever needed anyone to talk to, if our dad got upset with him again or started shutting down his emotions. But I haven’t heard from him. I feel so so much for him, it tears me apart to know he could possibly be going through what I went through, I want to save him from it but can’t. I don’t know how to bring it up to my parents, but I want to do so since they’re becoming a bit more self aware through my mental health journey and now my dad’s. Has anyone else experienced this, wanting to help a younger sibling in a similar situation? I really need some tips. Thanks guys &lt;3
