Hi Sam & welcome to the forum.

It sounds as though you've done quite well with taming so far so don't feel so bad, it's not unusual for young hamsters to be difficult to hold, they have far too much energy & would rather be running around exploring or hunting out treats than sitting still in a human hand!
I think you just need to give it time, as Flowerfairy says use a tube, or a ball or mug will do, to transport her to the bath or other play area & let her spend time running around on you, she should eventually calm down a bit more & allow you to hold her but go slow, one step at a time.
