Hi, friend!
First of all, do not deviate from your plans. If you only wanted to play 2 tournaments with a certain buy-in today, you must be prepared that they will not necessarily be won. Losing is unpleasant - especially when the chips were already almost yours and the opponent got the right card on the river.
Remember one thing, the desire to win back will never lead to good, and emotions can only be learned to control over time.
Be patient enough and everything will work out. Poker is not only mathematics and strategy, but also a discipline.
