Venting place?

Sorry

I feel like people think I'm just making up excuses to get out of work. They don't understand what a struggle ADD is. They they think I'm just lazy. I wish I could tell them without feeling awkward/rude how much this effects my everyday life. In class i wasn't paying attention because i couldn't pay attention not because I didn't want too. When I couldn't remember that obvious question it wasn't because I didn't study, but because my brain 'shut down'. That time I had my phone in my hand and was looking down. I wasn't playing on my phone or texting or anything, I was just staring at my phone and trying to concentrate on you or whoever is speaking. I don't try to be rude, but I have different ways of being respectful to people than others.
