Hi. I think I have mild ADHD. The main symptoms that I get are being forgetful and making careless mistakes, as well as fidgeting constantly. My mum gets really annoyed at me for forgetting things all the time. she makes me feel awful that i do and shouts at me all the time. she thinks that i'm not trying and that i don't care but i really do and i'm trying my best i just can't help it. today she got mad because i put a message on a small group chat with 4 of my friends on it inviting them to come and sit in our garden and i invited 1 person who isn't on the chat. i forgot that about a week ago another person got added to the chat so it now had 5 people on it so i invited 6 people plus me. I forget other stuff all the time as well, like handing in my homework or forgetting when deadlines for things are. i don't think it would be that bad if she didn't get so mad and just tried to help. i really don't want to tell her that it think i have ADHD though because she would just say that I was making excused and not believe me.
does anyone have any advice to not forget things so much?
