Losing in gambling are normal bro.
I also lose more than I win but I am not bored with it because it's fun and yeah, I can control myself even I lose always. Maybe put some limitation or have a budget always when you're playing so you can control yourself.
If you really bored with gambling maybe it's time for you to find some another habit or activities other than gambling. Why? Because you're not having fun anymore and you lose your money always. It's not healthy for you too

We have bad day ang lucky day.
If you lose always that time, it's not your day. Maybe get some rest  with gambling and try again tomorrow. Always Don't forget to put a budget so you know how much you loss
