This is not meant to be rude, but serve as a reality check.
I could be wrong but I have a feeling that both times you built your roll by going on a massive heater. Then when the heater stops, you get frustrated and go on a donky tilt and lose it all.
If you truly want to save your roll, then you have to accept that poker is one huge ****ing massive irritating mind blowingly dull
grind.
There is a saying in poker that if you are bored then you are playing good poker.
At 19 I would also guess that $1000 is rather a large sum for you and you think beating poker is easy and will provide you with a really nice income far surpassing you college friends. You need to understand that playing winning poker consistently takes many many thousands of
hands of practice and is not at all easy.
Follow proper bankroll management and understand that there is no easy "fix" to your problems. Learning not to donky tilt comes with experience, and with experience comes consistent profits over a large hand sample.
