No, there is not enough mass to that toy. I doubt it left more than a skin contusion.

Your concern should not be about the impact from the toy, it should be about your explosions. This condition has been called intermittent explosive disorder (IED). There are drugs that can help. You put yourself at risk of all kinds of injury with your outbursts. Even more is the risk of criminal behavior that can result in arrest and incarceration. Incarceration is very dangerous for somebody with PCS and IED.

These are the issues I am speaking about when I said 'You have more than stress to resolve.'

Your sense of a cognitive setback is far more likely to be a result of the rage and not a concussion.
