New Hobby Blues

I recently picked up knitting to unwind after work and find something creative to do. I thought it would be relaxing and maybe even fun, but every time I sit down with my needles and yarn, I get so frustrated! The patterns are confusing, the yarn always seems to tangle, and every time I think I'm making progress, I end up unraveling half of what I did because I made a mistake. It's like this weird mix of excitement for learning something new and dread over facing another tangled ball of yarn. Am I just not cut out for knitting? Or is it normal to feel so overwhelmed when starting a new hobby?
