Look, I've tried the "use drugs to feel happy"-approach. I've been addicted to Tramadol, and I've also abused a variety of benzos and z-drugs. Trust me, that shit doesn't work. Yeah, sure, the drugs will make you happy while you're on them, but if you rely on drugs to make you happy, the time inbetween, the time when you are sober, will be pure hell. The only thing you think about is when you're going to get high next. After a while, the temptation becomes irresistible to take drugs more often, eventually you will be sitting there taking Xanax every day, which will fuck you up completely so you can't study, you can't work, and you can't have a proper social life. In the end, drugs WILL ONLY MAKE YOU FEEL WORSE if you use them for this purpose.
