need expert opinion

Hello I need information on a specific name/strain that I need. My brain functions in a weird way am not able to think things clearly but when I smoke a certain weed I'm able to focus 100% on my life's issues and think-process-and make decisions! I've smoked 3 diff ones lately but not what I need. I'm looking for something that'll make me feel low/slow and to be able to focus on thoughts. I remember I smoked one "type" once and it helped me think clearly it even helped me focus on music's instruments you would not hear while high. So my question is, what name or strain should I look for to get this high? I don't even know if it was "chronic" so anyone with expertise please point me in the right direction, I NEED THIS. Thank you!
