For me, frustration is being unable to make myself speak in certain situations.
Frustration is being shouted at by teachers for distracting other students when i have done nothing wrong and they were the ones trying to destract me.
Frustration is trying to work through dissociation and reading the exact same sentence over and over and over for 2 hours and still being unable to understand or remember it, while being told to just stop being lazy and focus.
Frustration is trying to explain to teachers that the reason i never do my homework is because any time i tried, it never ended well when i was to afraid by that point to say anything.
Frustration is people triggering a panic attack when they try to pressure me about doing certain things and having to try to explain enough through the shaking, tears, and fear so they hopefully back off before I have a flashback.
Frustration is my jackass ex-landlord fucking us over by locking us out of the house a day early, calling animal control, framing us for animal abuse, causing me to have to jump through hoops to be allowed to get cleared to pick my ESA animal up, almost lose him anyways because we barely got there before the 5 day hold time was up, and we ended up having to sell several sentimentally important items to afford all of the fees to pay to get him released from the place they were holding him.
Frustration is having 6 different professionals in a row all tell me i have a disorder and not one diagnosed me with it.
Frustration is being unable to get/hold a job because of that disorder and being unable to really do anything about it.
Frustration is trying to find and afford someone willing to diagnose it and get it recognized as a disability so i can start the process of getting a trained and certified service animal.
Frustration is having to rely on others and be a burden because im as of now unable to have the tools to be able to survive otherwise.
