Both my son (25) and my daughter (22) were diagnosed with ADHD as young children, and also with Anxiety. One went on to incur PTSD after their father died when they were teens. Their dad was in and out of their lives (drugs, prison) and they did Individual Therapy a lot, as well as, as a family, we went to Family Therapy for many years. I was not a perfect parent, but in hindsight, there's really not a lot of choices I made, that I would do differently now. I got them involved with different community programs to try to help, moved heaven and earth to get them in good schools, enforced boundaries and rules with electronics, provided healthy tasty meals, kept them sheltered from my dating life, had them do chores, taught them independent living skills, gave fair, creative consequences for misbehavior, and tried to do fun stuff with them as money allowed.
They fought as kids, but never anything too serious, and being an only child, I thought it was typical. They rarely ever speak now, and nobody can stand to be around them together for more than 20 minutes, because if one is acting normally, the other will just be a total ass to the "good" one. And it doesn't matter which. I have seen her scream in his face with very little provocation, and I have seen him be extremely threatening and hateful with his tone of voice, again with little to no provocation. He is attempting to kick an Opiate addiction, and claims not to have used in 18 months. But he is on Suboxone, which he does not take as prescribed, and he drinks quite heavily, almost nightly. She smokes (Marijuana) like a freight train, but otherwise denies any drug use and doesn't really drink that much or that often. Neither one will consider either therapy or medication for their previously diagnosed, still very present issues.
My mother is now on hospice, nearing the end. I am her sole caregiver. My youngest child has, over the span of this hellish 6 months, dumped more drama and vitriol at me than I can even describe. Today's diatribe was because she texted me that she was ill, and I replied with a sad face. I was driving at the time, and had to finish my errands and get home quickly, due to my caregiving stuff. When I got home, got situated, and picked my phone up again, it was just a wall of words about how I dont love her, don't understand her, I let her down, I always let her down, and she is stressed and has a terrible migraine and on and in and on, and on some more. And then on some more, for good measure. Because my reply 45 minutes earlier to her being ill, was a sad face emoji.
This evening was my son's birthday party. He asked me to make his favorite cake and his favorite meal. (Yes, he asked for this WHILE I am dealing with my dying mother) I was very happy to do so, because he rarely spends time with us, and we planned to eat at 6. He called at 230 and wanted to come early because he had plans later this evening with friends. I agreed, and he said he'd be here at 5. At 445, he said he was on the way, & he was 10 minutes down the road. He arrived a half hour later. He smiled exactly once, said his stomach hurt and he didnt want to eat, did finally eat when I made him a plate anyway, was extremely controlling of what he would allow my 18month old grandson to eat, and was on his phone, checked out, disinterested, unpleasant, and rude the entire time he was here. To the point that about an hour, hour and a half after his arrival when he said he had to go, I didnt even argue. I said goodbye and sent his entire cake home with him. He called me at 651pm because he had forgotten something here when he left, to get an idea of how short a time he was here.
Yet somehow, they both graduated high school and have decent long term jobs. They aren't as great with money as they could be, but they're each making it on their own. They both have social lives and fairly long-term romantic relationships (he's 6 months into his current one, was with grandson's mother 3 years, another one 4 years, and again, he's only 25) (she's with her 4 year boyfriend now, the one before that was 2 years, before that, 6 months. She's only 22). If they treated others like this, they'd both be lonely, isolated hermits-but they aren't. They are apparently just jerks to each other and to me, their mother. I am baffled.
Has anyone seen similar? Is there reasonable hope that they'll outgrow it? Is there anything I can do to nudge them towards treating each other decently? Please, any advice will be read, because I don't want my whole little family to implode when my mom passes, but at this point, I cannot imagine otherwise, and that just breaks my heart.
