Took bath salts drug years ago, lost all pleasure in life. got better. brought it back by abusing adderall (dextroamphetamine and racemic amphetamine). now left lifeless. dopamine?

See psychiatrist: Get all of this addressed ASAP. Do not allow this to get out of control any further. Things can improve, but misuse of drugs is a dismal choice. Get a second opinion and proceed. Best of luck.

Bath salts: Can cause your brain to stop producing its own neurotransmitters. I would continue to work with a doctor to address the depressive symptoms present.
