How do i learn to move on...?

...from things that seem to paralyze me? I.e., parents' divorce, failures I've tripped on along the way, etc.

you could try something like couselling...if thse problems are really weighting you down, talking about them and getting them off your chest could help you a lot.
try to realise your parents probably got divorced for a reason...eg...didnt love each other anymore, ect...and this is normal, many peoples parents get divorced...my parents got divorced when I was about 8.
as for failiures, everybody can relate to that, we all make mistakes
and making mistakes is part of being human
its very normal, and very common, but thats how we learn...
from making mistakes, and hopefully in the end they will make you a stronger person
you could work thes eproblems out by yourself or talk to somebody like a counselloer, friend, parent, relative, teacher, ect about them
