My fiance is upset with me. She has adhd which probably plays a part in this. I'm sorry if this doesn't make a lot of sense I struggle to get my thoughts out properly. 

It started off because I woke her up 1 min before her alarm. I've been awake since before 730 and her alarm goes off at 830. She typically snoozes it a couple times before actually getting up. Today I only heard her alarm go off once and it was almost 850 so I thought I should make sure she didn't accidentally dismiss it instead of snooze cause she's done it before. 

An hour or so later she claims to be over it but I'm still upset she got mad at me for trying to help. We have to do my T shot and she brings everything to me to get it ready. Then she just completely forgets about it. Then I'm a passive aggressive asshole that probably made her feel stupid. But I truly don't understand how she can forget about the needle we do weekly, that she gathered everything for, and while we're still in perfect view of each other. 

Next I asked her what time she's going to work tomorrow. She used to work from home then we moved and now she has to walk to her mom's place to work. She said probably about the same time she leaves for school which is 11 am. I ask her why she wants to work until 8pm and she says she doesn't really care. I know that's bullshit cause before we moved she'd complain about having to work so late. 

She also gets upset with me for pointing out she shouldn't keep putting off school work because 90% of the time it leads to her being overwhelmed. But she always says that won't happen this time and then it does. 

How do I talk to her about these things without being a complete piece of shit and making her feel stupid?
