How do I stop the scale from being so damn demotivating?

I've started going to a gym for a week now and when I measured today I’ve lost only 0.3kg but decreased my fat by 2.0% and gained 2kg muscle mass? I know its a good thing, but i just can't help being disappointed there wasn’t much a difference on my overall weight lol. Can someone pls explain this? Will you be able to see results still if fat is replaced with muscle but you gain the same? I know this is stupid lol but i need some motivation as it all went to hell the second i saw the numbers on the scale
