If you need to abuse drugs for any reason, whether it is to relax, sleep, stay focused, whatever - and regardless of whether it's street-type drugs or prescription drugs - it means there is an underlying mental health problem. That's just the way it is. People do not engage in such desperate, impulsive and potentially dangerous self-medicating endeavors unless their is an underlying problem. You may very well not have bipolar disorder specifically, but to think that you don't have any mental health problems is pretty ridiculous given such behaviors as abusing Adderall to stay focused or smoking weed to help you sleep or relax. It means you are instinctively trying to medicate yourself, because there is a problem.

Sorry if I'm coming across as scolding or judgemental, I'm just a very candid communicator. I know that sometimes people need reassurance and empathy and some kind, gentle words, and there seem to be plenty of sweethearts on this forum who can provide that. But sometimes people need to hear it straight with no sugar-coating, and that's more so my niche. And point-blank, you do have mental health issues given your behaviors.
