<human>: Condense the text into a few key points

I'm extremely forgetful. I've tried various strategies to improve on my memory; I'm currently using a day planner, a large wall calendar and trying to use an online calendar but it really varies if I will remember to check these things or write in them. 

I am also not good at living according to a consistent schedule. My bedtime varies, I will wake up really late in the day if I don't feel like getting up and I will cancel plans or not attend school if I am too tired.

I'm diagnosed with ADHD and I am taking medication which helps, but if I get up too late then I can't take my medication so I remember to take it around half the time. My life is a mess.

All these problems are really affecting my relationship. I constantly forget about plans I have made with my SO and it really hurts him. Today I forgot that we were supposed to have dinner together and I also forgot to wake him up at 11AM because I slept until 1PM so I wasted his day off.

We aren't on the same schedule right now and time together is really scarce and I am making it worse by not being a functioning adult. I know I'm really failing my partner and hurting him but everyone just tells me to get my shit together and I don't know how to do that. It seems like everyone can intuitively use a schedule and keep plans but I don't know how. 

Please help me figure out how to do this. I know I am failing my partner and I need to stop.
