Hello Erecura.
There are meds for this and a lot of them are for parkinsons disease or parkasonia. They found thes people have low dopamine levels. I don't know of any test that can determine that you have low dopamine or any other chemical. Rexulti is a dopamine re-uptake inhibitor. I think the add meds also are in that class. I think your kinda hard on yourself calling your self lazy. We often can't do things we like so that is a good indication your not lazy.
