Well I learned something tonight. After a couple long tournaments don't take your cash to a cash table. At least for me it was a bad idea. I was tired and made bad decisions. I could tell I was mentally tired but I wanted to keep building my bankroll and that was a huge mistake. I lost it and not even to bad beats just bad play. So for now on Im gonna take a rest after long tournaments and anytime I feel tired. So good lesson for tonight. I got to remember this. Anyone else experience this let me know

YES a long tournament can be mentally tiring !

If you are skilled enough to make it past the 2nd break for sure .
However jumping to a cash table soon after to continue a roll is not a great idea.
Taking a break would be advice. There will always be another game another day .

If you are scared of cash tables don't be it is where you can really get the true skills learned to use in the bigger tournaments.
Maybe starting at  very low  tables or low Sit n GO  - Everyone is different though .

Sounds like you were playing more for a luck streak then a true building streak .
That in itself can not be good especially after a tournament. Each game / players and styles are different at every individual table .

Better luck next time -
