You will have far more losing sessions than winning ones. Accept it, but don't worry about it. Individual sessions are meaningless. $1,000 playing $25 a pop equals 40 bets. A n okay rule of thumb is having the equivalent of a Royal as bankroll. Your bankroll is equal to a quarter Royal, not a $5 Royal.
Playing with 5% of the recommended BR puts your risk of ruin in the stratosphere. With that BR, the most likely scenario is you leave dead broke.
Losing $1,000 of a $20,000 BR hurts. Losing your entire $1,000 BR sucks.
