Is ADHD really this bad?

So I've known that I have ADHD all my life but never knew the symptoms other than being hyper and can't focus. But I've become more interested and found that ADHD causes a lot of different stuff and has a lot more symptoms and disorders involved... And as I looked, I found that most of them are happening to me. Depression, lack of focus, hyper, eating disorder, RLS (restless leg syndrome), bad memory, zoning out, hyper focus, emotional, can't think things through, shy, addictions (like constantly popping fingers or obsessing over things)... Now I feel like my life is just pure ADHD...

BTW I'm 17 (18 in March) and I have been diagnosed with ADHD and I am currently taking medication for it. This is probably just me having an emotional moment and wanting some feedback....
