Welcome to Just answer !
I am sorry to learn about your condition and i empathize with you.
Well first of all i will like to bring your attention to the thought behind addition of adderall and methylphenidate ( ritalin) , probably this is the drug which you are talking about , and that thought is to uplift your mood and provide you energy and enthusiasm as these two drugs are known as psychostimulants which are used at times with anti depressant drugs to elevate one's depressed mood and boost one's moral and enthusiasm and improve one's attention , focus and concentration as these drugs are known to provide all of this being psychostimulants.On a flip side these drugs are known to produce some self limiting side effects like nausea, vomiting , stomach upset, sometimes fainting too can happen.
Now before i provide you a plausible solution to your long standing problem, kindly answer a few queries.
1) Kindly mention the drugs that you are currently taking and also mention their respective doses.
2) Have you tried any counseling all these years , if yes what type of counseling ?
I will get back to you once you reply to my queries.
