Before I got slightly addicted to some drugs and also had depression before, so I hope my story could help you a little bit. Before, I did not have many friends when I moved into a new environment, it is hard for me to make friends because I am an introvert, therefore I drank beer, drinking helped me to have more courage to go to talk with others as comfortably as I want, however, of course drinking too much would not be good for sure, I got hangover and my work life, relationship...etc had been going down hill, so I decided to stop because I know drinking is a solution for a superficial cause, the root behind is I am an introvert, so if I want to make friends I should go find someone who may have similar characters to me and also learn from others even they are introverts or extroverts, people are nice to teach us and tell us what they know, so by that way I can make friends easier, and friends are not everything, I find to have a hobby, I would say a healthy hobby, what do I mean by that ? A healthy hobby could bring you joy, happiness, meaning, value... Such as photography which would break our ruminating thoughts especially negative thoughts. And by this way, I am able to avoid the drinking addiction as well. I think if we rely on something too much, we tend to get addicted, and without it, the symptoms may get worse I ssuppose. Im not sure about others, but I think we all have an addiction, thinking negative is also a mental addiction in my perspective, so why dont we choose another healthy addiction anyways? . i hope it is helpful.
