Facing an insurmountable problem,
you won't be able (at least mentally) to work without thinking about how difficult it is, at first sight, and it would systematically increase your fear too.
If you cut your big task into smaller and doable ones, sort & prioritize them, and work on it, one by one only,
you would be able to start working on this whole system by little iteration,
and fastly see progress.
You've just converted an impossible task into a super-doable one ;-)
It is totally natural / normal to feel fear when facing very hard problem (because a reasonable human should not try to face problem he can't solve).
Fear of failure is natural too.
Just try to simplify your life facing problems, by cutting off in smaller parts.
Your brain would appreciate a lot, and you won't follow a fear loop anymore.
This is big part of engineer job to face technical challenge like this one, and find efficient solution.
Just make this problem your friend, while monitoring completion time (your real worst enemy)
