Why is so difficult to leave that world of drugs and alcohol when life is more that that?

Because the drugs are doing their effect on you, making you think you need them. At the moment your body believes it needs it, like sugar or any nutriment or whatever its called. The moment you are going to step back from it, your body will be like " "duuude(tte) give me some morree"". Its going to be hard but if you make it through by replacing it by some legit activities such as going to a massage session, you shall be free my dear. Good luck, we wait you at the other end ;)

Because alcohol is your friend or you think it is, it will never let you down. It is always there for you.

Because drugs and alcohol and other narcotics literally change your brain. They release chemicals that make you feel better than you can naturally.

Sometime when our addictions have a vicelike grip over us, our sober friends and family leave us. While it may be intended to get us better, it can make everything else seem hostile compared to the blanket that the drugs provide.

Leaving a lifestyle of substance abuse is often difficult because addiction can have a strong hold on a person, both physically and psychologically. Substance use can create changes in the brain that make it challenging to quit, even when the individual wants to. In addition, substance abuse can lead to social, financial, and legal problems that can feel overwhelming. For these reasons, people may feel trapped in their addiction and unable to leave it behind. Seeking professional help, such as addiction treatment, support groups, and therapy, can be a crucial step in breaking free from substance abuse and building a healthier life.
