I take medicine. I couldn't function without it.
Aside from that, I take notes on EVERYTHING. I'm sure people think it's weird, but I just can't remember things and it helps me stay focused on what people are saying. If I don't do that then I lose focus and start to wander off to other things in the room or random thoughts or something. It gives me something to reference later when I just can't remember what the heck someone said.
I also have a pretty set routine. I wake up at the same time every day (I'll sleep in on weekends). I do the same things in the morning. I go to bed at the same time. It took me a long time to get the routine down or even want to do one, but doing it has helped a lot.
I have a Franklin Covey planner that I make to do lists in and keep track of appointments and such. That helps me stay on track with what I need to accomplish each day. If I don't do that, I get distracted with random things and get nothing important accomplished. It keeps me organized and on task. They're expensive, but totally worth it. Oh, and I don't forget appointments that way. Because I totally blank on things like that.
I still have issues, but they're made a lot better with the combo of meds and organization. I know it's frustrating for people to deal with me. I can't remember things and I tune out when people talk. I get bored easily with conversations. I also get antsy when I go out and stay somewhere too long. I get bored with a lot of things. I also have Bipolar, so that complicates things further and makes me even more difficult. I have a select few people that are willing to put up with my eccentricities and hold them close to me. I don't go out of my way to make new friends or anything because I don't like to push my problems on people. I wouldn't recommend that. It gets lonely. That's more of the Bipolar than the ADHD.
If ever you need someone to vent to, just message me. I'm always happy to help.
