I have ADHD.
The biggest issue with ADHD for me is basically being overwhelmed. I can get overwhelmed by demands, overwhelmed by executive dysfunction, overwhelmed by my emotions, overwhelmed by things I have to remember, overwhelmed by decisions, overwhelmed by sensory input.
In terms of the sensory issues, I don't seem to have the ability to filter out thoughts or sounds or things that are going on from the thing I need to focus on. Say I'm in the lounge with my 2 children and they are each watching something on their tablet. My husband is in the kitchen listening to the radio. The TV has been left on. There are workmen in next door's garden. My husband is slurping his tea. I cannot filter out any of that, nothing blends, everything jars and it all feels like an assault.
If there are background noises and someone is trying to talk to me, I can't focus on what the person is saying. I get intensely irritated. I feel exhausted. So exhausted I feel like I could just lay down and go into a deep sleep. My brain wants to shut down.
I have RSD, which is common in many people with ADHD. Rejection sensitive dysphoria. Nobody like criticism or rejection, but to me it feels like a physical assault. I will feel it like a punch in the gut and it will totally overtake and overwhelm me. I will lash out verbally with and intense and powerful need to be understood and heard, and be accused of overreacting. I have very little control. Sometimes I will internalise it and feel deep shame.
I notice everything. The slightest change in tone, someone changing the conversation, a sideways glance. Things people probably have no idea of. I will presume people are laughing at me and have intrusive thoughts about what someone is thinking about me. If I find out people are talking about me behind my back it is like my worst fears realised. I presume people don't like me, won't want to see me. If someone doesn't come back to me I will feel I've upset them, feel ashamed and like I've done something, feel the impulse to apologise for it. Often I do and people are like "I was busy you weirdo you're fine". But I tend to blame myself rather than other people, I don't think badly of people generally, but do believe people think badly of me.
Erm... not sure what else you want to know so if you have any questions fire away.
Oh, although I struggle with getting my brain to focus on the right things, I am capable of very intense focus and of being incredibly productive. I am amazing in an emergency. Adrenaline gives me the most insane clarity of thought, it switches on my brain and I notice everything, process everything so quickly and efficiently and just know exactly what to do. I should probably be in the emergency services or something - but then if I've hit a wall and my brain doesn't have anything left I'm absolutely useless so maybe not.
