adhd demands stimulation in order for you to function and depression takes away the feeling of stimulation leading to perpetual nothingness   perpetual nothingness that causes a lot of stress due to inner restlessness although that may be mostly because of my inattentive type   i was diagnosed with dysthymia combined with my add the feeling that  youre always performing sub-par even on your best days and that there is no resolution can be crippling ive spend days if not weeks as you say blankly watching one youtube video after another while contemplating on all the things i should have done should do want to do but never did or never will do and even then i sometimes ended up completely overstimulated just by my own ever rolling thought train   took quite a lot of therapy to get beyond that point and even now i still need help every now and then to keep my life on track but trust me it is possible to get through it funny enough my meds did help a lot not just because of what they do but also because of what they demand i take dexamphetamine dont know englishamerican names and since one pill only works for a few hours i take them at regular intervals it takes quite some effort but that and that alone brought a certain rythm in my life that really helps me to keep up my better habits and yeah therapy
