Исправьте пожалуйста ошибки в тексте!!!!!!

Hello, dear group mates / friends!
My name is Irina and I’d like to present the article that I refer to the behavioral perspective in modern psychology. The article by Anna is titled ‘Confessions of a former drug addict.’ The main idea of the article covers is that drugs are evil. The article is a warning to those who have not used drugs and for those already using drugs, the article is an example of what will be their life with drugs. The text is an interview with a former drug addict.
Summary of the text:
In the first place the author tells what started the addiction to drugs and why the hero to use them. Everything changes the behavior of the hero and his relationships with family and friends since the drug use.
The addiction begins to control the thoughts and actions of the hero. He spends much time in prison.
The drugs for a long time was accompanied by Andrew but he managed to cope with the addiction. He radically changed his life. He developed new Hobbies, new friends and favorite job.
The author believes that it is important to convey to us the idea of what drugs to anything good will not. The drug use threatens people with drug addiction, prison or even death.
The author doesn’t refer to a range of sources, all written on the stories of Andrew, a former drug addict. This fact allows us to conclude that the article is not fictional. There is a real hero, who by his own example and told how changed his life at all stages of addiction.
In conclusion, I want to say that we should not repeat the mistakes of other people, you need to learn from those mistakes. Protect yourself and your loved ones.
