First, Diamond, props to you for posting this. This isn't always easy to do.
Secondly, I've had symptoms of ADHD for most of my life, which got a lot worse in the past five years. I have a job that requires a lot of focus and concentration, which was slowly becoming impossible to do. The symptoms I have are brain fog and forgetfulness, which lead to a lot of anxiety.
After a break down last summer, I went to talk to my doctor. It was painful. I'm the type of person who believes that willpower can solve most, if not all, of life's problems and I was convinced I could will my way through this. I didn't want to be medicated, because I thought medication meant, "broken."
What she said to me was pretty fantastic: "There is nothing wrong with medication. There is nothing wrong with the way your mind works. It just works differently and all this medication is going to do is help it catch up when a lot of your focus is required." That really spoke to me, so I tell people I have it as it comes up, especially if I bounce from topic to topic or get a little forgetful as the medication wears off, usually late in the evening.
I would actually like to thank my RP partners, because during this time (around September and October), I was adjusting to the dosage, which caused some interesting moodiness. Sindome became a place of refuge during that time. It provided a bit of escape until everything situated itself. My character is very different from me, and honestly, playing that character was so helpful to not focus too much on it. It was beyond therapeutic, which seems weird to say considering our theme. Due to certain plotlines, I was able to adjust the personality a bit, since the character was created before I started the medication, so as far as that is concerned, take any IC event you can to make adjustments as you need.
Overall, I feel profoundly more like myself than I have in years. It's become apparent at my job, my personal relationships, and my friends. I've even made some new ones on the way! It's allowed me to be creative again, which I've pushed back into Sindome. Overall, it's been worth it.
Drop the stigma and take care of yourself first, through whatever path that may be.
