Very relatable. One thing that helps some people is treating the “second job” like any job: cut the tasks, not just push harder (I’m on a medical editorial team that writes about ADHD, so general ideas, take what fits):

• Pick 2-3 systems, drop the rest. A calendar with alarms, one capture inbox (notes app or paper) and a weekly 15-minute review cover most of it. Ten half-used apps are their own workload.
• Automate the boring part. Auto-pay bills, recurring reminders, pill organiser or a phone alarm for meds, groceries on repeat order. Every decision you never have to make again is attention saved.
• Make the environment do the work. Keys always in one bowl, a “launch pad” by the door, the gym bag already packed. Less remembering, more defaults.
• Protect sleep first. Short sleep makes every ADHD symptom worse the next day, so a fixed wind-down alarm often pays back more than another productivity trick.
• Body doubling and external accountability (a friend, a coworking call) can replace a lot of willpower.

And it is fair to be frustrated. It is real extra work that other people don’t see.

Good luck on Monday! Here’s roughly what adult assessments cover, so you can jot down examples without rehearsing answers (I’m on a medical editorial team that writes about ADHD, so general info only, clinics differ a bit):

• Childhood. Symptoms need to have been there before about age 12, so expect questions about school: reports like “could do better if they tried”, losing things, daydreaming, unfinished homework, trouble for talking or fidgeting. Old school reports or a parent’s memories help a lot.
• How it shows up now, in different places. Work or study, home, money, relationships. Concrete examples work best: late bills, abandoned projects, lost keys, missed appointments, interrupting, hyperfocus on some things and paralysis on others.
• Impact. Not just what you do, but what it has cost you: jobs, deadlines, fines, conflicts.
• Other explanations. Sleep, anxiety, mood, substances, thyroid. Answer honestly, it doesn’t count against you.
• Questionnaires. Often the ASRS, sometimes one for a partner or parent too.

Practical trick: a one-page list of real examples on your phone, sorted childhood / work / home, and tell them at the start that you blank in the moment and made notes. Clinicians are used to that, honestly it’s pretty on-brand for the assessment :)

I hope this got sorted since you posted, but in case it helps you or someone else stuck in the same gap (I’m on a medical editorial team that writes about ADHD, so general info only):

• The practice is responsible, not just the one psychiatrist. If she works in a clinic or group practice, call the front desk and ask who is covering her patients. Clinics usually have to arrange cover for an absent prescriber, and a colleague can often issue a bridging prescription based on her notes.
• Ask for your records in writing. The screening results, the diagnosis and the trial notes belong in your file even if the formal letter wasn’t finished. With those, a new psychiatrist or a GP-with-shared-care can pick things up much faster than starting from zero.
• Rationing tells you something useful. The fact that the old symptoms come back within a day of missing a dose is exactly the kind of detail a new prescriber wants to hear, so jot down what you notice.
• The part about suicidal thoughts and self-harm matters most. If those come back strongly, please don’t wait for the ADHD paperwork. Your GP, an urgent mental health line or emergency services can help with that right away, separately from the prescription issue. In the US, call or text 988. Elsewhere, findahelpline.com lists local lines.

Feeling “normal for the first time” and then losing it is genuinely hard. It’s a good sign that you found something that works, though. That usually makes the next prescriber’s job easier.

A few things that are useful to know when you go back to your doctor (I’m on a medical editorial team that writes about ADHD, so general info only):

• The two drugs work on different timelines. Methylphenidate acts within an hour or so, but people almost always start on a low dose and go up step by step, so day 4 is often still below the dose that works for you. Atomoxetine is the opposite: it builds up slowly and often needs 4-8 weeks, sometimes longer, before the full effect shows.
• “Working” is often quieter than people expect. Many describe it less as feeling different and more as: starting tasks with less friction, fewer half-finished things, not losing the thread in conversations. It’s easy to miss from the inside.
• A tiny daily log helps a lot. Dose and time taken, hours slept, focus 1-10, appetite, mood, anything odd (heart racing, trouble sleeping). Two weeks of notes makes the follow-up appointment much more productive than “I’m not sure anything is happening”.
• Sleep and caffeine can mask the effect. Short sleep makes almost any ADHD med look like it isn’t doing much, and a lot of coffee on top of a stimulant can just feel jittery rather than focused.

The dose and combination are really your doctor’s call, but going back with specific notes is the fastest way to get it adjusted. Good luck, it often takes a few rounds to get right.
