Hello! I have severe ADHD. It's the variant without hyperactivity, but in the newest DSM ('official' list of known disorders), they've combined ADD and ADHD into one (ADHD), as they seem to be variants of the same disorder (i.e. not two different disorders).<p>The single biggest thing that worked for me was medication. I can very much recommend. Please ignore people that say that you 'can work through it', or that handling things without medication is somehow 'better' or 'more natural'. This belief is stupid, wrong and needs to die.<p>The annoying part about mental health is that problems aren't visible. You would never tell someone with a broken leg to 'tough it out', or ask a disabled person to run a mile.<p>If you're diagnosed with ADHD it means you actually have a mental handicap / impairment. Just like someone with a broken leg, it needs medical attention.<p>Before I was diagnosed and got medication, I've tried every tool, every method, every strategy to organize myself, keep focused, or otherwise mitigate my problems that I was having. From GTD, todo lists/apps physical and digital, bullet journal, pomodoro, meditation, cold showers, making your bed everyday, journaling, the secret, etc. Basically all the things people are recommending in this thread.<p>I couldn't keep up with any of them. The biggest flaw in most of these systems is that you already need to be very much organized to effectively integrate these in your daily life. It never worked, and after a couple of months of trying to integrate such a new habit I would ultimately fail, and hate myself for it.<p>Since mental health plays a part in every aspect of life, this mechanism permeates all facets of life. It's hard to keep up eating healthy, playing sports, finding time for hobbies, working, keeping up with relationships, sometimes I even had difficulties keeping my attention while I was talking to someone, leading to some very awkward discussions sometimes. Ultimately it's VERY EASY for untreated ADHD to lead to depression like this, as it did in my case.<p>Only after I've started getting this chemical deficiency sorted by using medication was I able to really feel like I had any meaningful grip on my behavior.<p>Please, please, please! Don't make the same mistake that I made, and get tested for ADHD, if you think you might have it.
