I'm going to try and keep this clear and concise.

I'm not confident in my parenting. I don't feel like I've been a good parent, but I have done the best that I can with the tools and resources that I have.

My 18 y/o has lived with us since she was 4. My partner has been in my 18y/o's life since they were 13 months old.

18y/o is copy->paste of their deadbeat mother and I don't know what to do about it. I don't know what I can do about it at this point.

I have tried to instill structure, while allowing wiggle room at times. I recognize that it's my job as the parent to draw hard lines and it's my kids job to push the boundaries and cross those lines.

18y/o is almost mute around us. Doesn't communicate much of anything beyond surface level 'pleasantries'. And it's more often than not, anything but pleasant. They (biological female) are diagnosed with ADHD, 'change disorder', anxiety and depression. I've done so much reading trying to figure out this person and how I can help, but nothing seems to help. Kid has never really be honest with therapists. Lies for no reason, and doubles down even when presented with irrefutable evidence that they've been caught. If I had to 'self-diagnose', they have ODD and are a sociopath, but I've seen how they behave around friends and peers. They only have disregard for us. Outside the home, they are a people pleaser. But if we suggest something, or ask for something to be done, it's a fight, every time.

They are a senior in high school, is a good student when there's nothing rocking their boat, but had steadily declining grades as the school year presses on. I have no idea what's going on in their life, everything is responded to with a random selection of the following list:

I don't know

I don't remember

I don't know how you want me to answer that

Do you want me to respond?

I don't see what the problem is.

I don't see how this is a big deal.

The current argument is regarding whether we should be expected to wake them up for school in the morning. I've already put my foot down about it, and since December 1st, they've already walked themselves to school twice because they overslept.

They are impossible to motivate. When things finally come to a head and an argument breaks out, which typically boils over because there can be no constructive conversation with someone who is either unable or unwilling to have a conversation. And only when the argument breaks out do we get any action on anything, and then it's an overcorrection. For example, we've been pushing for them to fill out scholarship applications for 8 months. We've had friends provide spreadsheets with links to what we collectively think are viable scholarships, for no action responses. Then when we finally get a break in the wall, they fill out scholarship applications for tens of thousands of dollars for enrollment in a school states away with misleading GPA information. We are not in a financial position to accommodate that kind of enrollment, even if we wanted to support the decision. It comes off as an "I'll show them" move.

Nevermind the drivers license thing. Can't get them to get off their ass and get their license. It's been a battle for 2 years. Something always goes wrong. Last time I pressed on it hard, we ended up in intensive outpatient therapy.

They're unmanageable and I don't know what to do for or with them. Our home is small, 800 sqft and it's a hell hole. My partner has almost left me twice over this kid's behavior over the years. Partner and kid do not get along at all at this point, and has lead to a false CPS report so my kid could try and move in with their crush's family.

There so much context missing but there's no time or room for 18 years of back story.

I don't know if there's a question here, but I need help or support, or something. Any stories or advice anyone cares to relay would be appreciated. I'm terrified that once this kid leaves, I'm never going to hear from them again. But I can't control that, and I recognize it.

Thanks for reading.
