Worried Sister, your post hit me right in the heart because I am going through a similar situation. What it all comes down to is that your sister has to be the one to make the change. There is nothing you can do if she refuses to face her addiction. The TV program INTERVENTION is a good source of information as is Al-Anon. By helping her during these self inflicted crises you are prolonging her misery. It will be hard to not help her, but you must let her know that if she does not agree to treatment or stop her Adderall abuse on her own, you will no longer be available to her. It is tough love and the only thing you can do to help her. Can you get your family to arrange an Intervention?
I am struggling myself on a daily basis to finally stop this horrible Adderall addiction. I have quite a few friends who are also taking this drug that I find it extremely hard to completely quit. Sometimes I just want to run away for a few months, get healthy again and get my real self back.
What breaks my heart is seeing how it is destroying my younger brothers life. He has completely changed since starting this drug years go. He is constantly on edge, antisocial, and looks like he has aged 20 years in 5 years. He is also in denial and actually thinks he needs the drug to live his life and gets defensive when confronted. I know what you mean about the health problems, this drug destroys your immune system, causes heart damage, and accelerates other chronic diseases. But what it destroys most is the most important thing in he world-- self love and the ability to love others.
Good luck and keep in touch, this site is an invaluable source of information.
