Uhh draw a circle.
But seriously here's my best advice for getting started again: Typically when I get back into drawing I just start off with drawing what I like, then once I get back into the groove of things I'll start working on the fundamentals. Starting off with the fundamentals can be boring and offputting, so try to pick something that you're interested in drawing, and then learn the relevant skills required to draw that subject to improve from there. I recommend George Bridgman's books on anatomy as a good starting point, at least if drawing human(oid) figures is what interests you. Also Youtube is always available, just look up "How to draw X" and you'll find plenty of tutorials. Just don't overdose on Youtube tutorials, try finding one or two artists and learn from them, otherwise you'll get too much advice that sometimes contradicts each other.
As for finding motivation, that's something you'll have to find in yourself. If you have some free time, just try drawing something that interests you and see if you enjoy it. If you do, you'll want to do it on your own and you won't feel like you're forcing yourself. Right now it seems like you want to draw, but you're holding yourself back with excuses because you're afraid you won't be good enough. No one's ever good enough at first, just stick to it consistently for a long enough period of time and see where that gets you in a couple months or a couple years. You can always post your art here and get feedback, no one's going to shit on you for it, and if they do, fuck em'.
