My Brother Is On Medication For Anxiety And Depression And

my brother is on medication for anxiety and depression and is now like a zombie, he doesn't respond, it is like he is living in his own mind, and I don't even feel safe with him when he is driving, it is like his focus is not accurate, I think that his psychiatrist doesn't take this situation seriously, he should be asking his family how he is doing, I want him to change the medication he has prescribed him, don't know what kind but it can't be good for him mentally if he is not alert and has no interest into anything, his house looks like a pig style, his new car is as bad, the yard looks like a junk yard, he used to be a cop and wasn't able to go back to work, why is there not follow ups with the families?
