Here's some proof that Ina has clear anger issues, when the creeper blew up behind her and made a hole, she had to stop to practice deep-breathing exercises for 5 minutes and "Stick with 'I' statements", which means to avoid criticizing or placing blame. These are clear cut methods for people with deep anger issues.
And during her Hade's stream, after accidentally getting rid of an important item, she had to stop and mute her mic for one minute because she was raging that bad. She even forgot to "stick with I statements" and placed blame on Nintendo and PS4 for "not having their buttons backwards". If you hear closely, she had to reconnect her controller, which shows evidence that she likely threw it during her rage fit.
