I was hoping someone else would answer you as there are others on here who know more than I do about breaking in skates.
I would say hang in there, be patient, try to enjoy the process, skate as much as you possibly can, focusing on doing a few things correctly, as you've been taught.
Some people say to wear your skates off ice, with the guards on, at home - especially on carpet where they can't do any harm. If they are heat mouldable you could put them in the oven. Leave the top eyelet unlaced - you will get less support but more movement.
Any change in equipment will feel strange for a while, especially if you are a relative beginner.
Skating has been wonderfully rewarding for me. I am a slow learner, but 15 or so years later I am still going and enjoying it more than ever.
