The longer you play, the more you will notice "streaks"

It sucks to get lousy cards for any length of time.

It really sucks when you get good cards & lose with 'em, & can deplete your BR in no time.

Best advice I can give is to take some time away from the table & annalize your hands & your game. If everything appears reasonably solid, ya just got beat by the poker gods, gain confidence from this knowledge.

If you find you have leaks, identify them & take the steps to improve on 'em.

As far as I can tell, poker is about 30% luck. Luck is what keeps the fish fed!.....LOL. Accept that the 30% bad luck can happen for weeks!

Welcome to poker! It's part of the game.
