If you really want the meds, I reckon you can go see the second doctor and hope they don't realize, and if they do, you can just really chill say you're asking for a second opinion. For example at 2nd doctor: I have this, this and that mental health problem, would you think I need meds, if they say yes of course and prescribe them then you're done, and if they go but you're seeing xxx doctor already, just go oh I just wanted to see another and see if they'd give me the same meds so I know the treatment is reliable. I think either way this is safe enough
