I think I have ADHD

I'm constantly making mistakes at my easy job, I have a hard time focusing, I never reach my goals, and I always feel out of control.

How can I stop being forgetful? Gosh I feel like such garbage 😔

Every job I've ever done I've never done super well, but doing an office job is so much worse than the kitchen or cleaning job. I was determined to write reminders for myself, then I forgot to write the reminder and forgot the conversation with my boss happened.

I've always been a dreamer but I did well in high school, I procrastinated doing homework but I was smart so things always worked out. I'm a mom now and I have a lot on my plate and I can barely hold everything together. I need to be guided constantly in my job. It's so embarrassing. If I have it and I tell my boss does that mean he has to grant me some sort of leeway with my mistakes?
