Any GenXers here ever been the target of emotional/verbal abuse by a sibling?

Has any other GenXers here ever been the target of emotional/verbal abuse, smear campaigns, manipulation attempts, etc. by a sibling even in adulthood? How has it affected you?

Have you found others to be disbelieving or dismissive of your situation or how damaging it has been to your physical and emotional well-being? Have you felt like others blame you or act like you‘re at fault for not stopping it? Like you had control over it even when you didn’t and your best efforts at standing up to the sibling didn’t work?

I’ve posted about my situation before on a sub regarding borderline personality disorder (BPD) — what my counselor suspects my older sibling has- but I was wondering if anyone here had been through something similar with their sibling(s). I see a lot of posts in various subs from people who’ve had parents or spouses/partners who were verbally/emotionally abusive, but not as many with a sibling who has treated them that way.

Just wondering what others’ experiences have been and how you managed to cope and overcome the feelings of anger and resentment at how badly they’ve treated you. It helps me, anyway, to hear from others who’ve been through similar circumstances.
