I have PTSD (RTS specific) and also suffer from Bipolar moods, and sensory/language processing problems.
The problem with Bipolar moods is that taking medication for your depression can only make you swing right into mania. It's a complex mood problem so it's not easy to treat.
My PTSD can cause anxiety spikes, anxiety attacks that vary in intensity and also flashback episodes.
Sensory/language processing affects everything I do. I can't use equipment or items that give me a negative sensory response because all my responses are extreme. If I catch a bad smell it can make me feel unwell, even if it's only a little. I can't use/wear/play anything that gives me a BadTexture.png because it causes constant misery. I can't be in a room that's too noisy or too quiet without getting sensory overload. I can't play certain games anymore (Marvel VS Capcom for example) because of too much happening on the screen, and whenever I play a game I have to adjust the colours or I struggle to see anything. If Street Fighter V doesn't have the gamma turned down, it makes me very confused.
I cope with my mental disadvantages by stimming normally - I use a tangle and some putty/slime kits. I really want to get a glitter/water ball, and some squishy things too. It helps me focus and steady my confused brain. I also practice various therapeutic exercises/treatments to help me keep my brain in order.
I have two comics at the moment. Art/writing is one of the few professions I can manage without suffering sensory overload, since most jobs available to people my age where I live are in noisy environments.
