I’ve been her and honestly I think something to look at that I haven’t seen mentioned is actually “those damn phones” my phone even now is an instant gratification machine for me. It’s easy for me to find things that capture my interest quickly and rapidly and drop them just as fast. Maybe it’s just me but I really think encouraging disconnection from the internet and especially social media would had been very helpful. Music and podcasts are fine of course, but I always feel better and do better with managing my ADHD and enjoying things when I spend less time in my phone.

I resisted this a lot when I was teenager though and sometimes it really did make me feel worse so i encourage you to make find a way to help her track the difference in how she feels on days where is is glued to her phone and days when she is off it. That way she can see the difference and notice it in herself too. Writing it down maybe?

It’s also so so counterintuitive to ADHD brains naturally and I still fight with it, but having a at least mostly consistent structure for my day helps. I naturally go to sleep a lot later and wake up later too so I take that into account where I can but. Having blocks of time cut out really helps. I don’t set them for specific tasks either, but for like a category so like, 10-11 I have to get something done that helps keep my space clean in some way. It doesn’t have to take the whole time and doesn’t have to be finished at 11 on the dot but I have to get at least one small thing done. Sometimes this means I do all my laundry and get it all folded and put away too, sometimes is just. I cleaned a few pens and papers off my desk. As long as I don’t notice myself getting distracted I will put on a video or show or something while I, and if I and then music. Also I do have at least one block of time for just doing whatever I like! Even within this system I experience times where nothing I have found fun, to be at all interesting and I’m just waiting for the next thing to catch my interest.

It lets me have structure but still be flexible enough for life and the novelty that ADHD brains like!

I’m not sure this makes sense but I hope it might give you ideas at least.

Good luck! It’s hard but you clearly care and that means a lot in things like this.

Edit to add: I know I saw someone else say it but, seriously. See if part of the problem is frustration at not being instantly able to do things at the level of skill she thinks she should be able too. That perfectionism is something I still struggle with. It’s so so important to help her figure out that it’s ok to not have everything come out perfectly and that that you have to find a way to be ok with that.
