Wow such a good thread!
I would say most new UXers (or anyone who's learning to do something new, actually) would go through the below "emotional rollercoaster". There comes to a point where you question your abilities a lot and are ready to give up (at the lowest point of the rollercoaster).
But, if you just keep going, keep asking questions, trying things and and working hard, eventually you will come out the other end with clarity. UX is messy, sometimes you will feel like you are going around in circles and getting nowhere, but that's all part of the process!
