Hello all! I’m very new to knitting, (so far I have only made a simple cowl with brioche stitch, knitted flat) and this is my second project ever. I know socks can be challenging as a beginner but they look so amazing and comfortable, and I just couldn’t resist learning how to make one any longer. At first, I tried using the magic loop method but I couldn’t avoid laddering with that so I moved on and tried using DPNs for the first time. After a day of looking up tutorials on how to avoid ladders on DPNs, I think I finally managed to make it look fairly acceptable, but I noticed that as my confidence grew with using DPSs my tension became tighter. And now when I picked up the sock to work on it a bit I couldn’t move the stitches on one of the needles. So I kept trying to gently move them and once I managed to do that I noticed that my poor little needle was broken 😞 Two of the stitches have fallen off but I think I was able to secure them and tomorrow I will pick up some new needles and hopefully I can transfer my work to them.
But should I switch to metal needles or stick to the bamboo(?) type I already have? 

Also, I’m using Drops Fable, and the suggested needle size on the label is 3mm but the socks patterns I bought and looked up all suggested 2.25mm needles so that’s what I’m using too, but not sure if it’s not too small for this yarn/my tension. 

And another question now that I'm already here; I’m doing k2 p1 ribbing for the cuff and I always thought that both sides of a ribbing were supposed to look the same, but in my case, they look very different. (pic 2&3)
Am I doing something wrong? 

Sorry for the (probably silly) questions, I have no knitter friends irl and I am still just trying to figure out this beautiful craft. 

Can you break a needle by having too tight tension?
