Matt's anger issues/depression

does anybody else think matt might be depressed? he's talked about his anxiety and mental health issues before so we know he's always struggled with them but lately he's been more moody and aggressive. in the "we drove from La to Boston" video, Nick bought him something from a gas station and matt got angry, grabbed it and threw it in the car while being super mean to Nick. he's also been way more physical lately, hitting mostly nick but Chris too. I do believe that anxiety is not his only mental health issue and that he would really benefit from going back to therapy.
