Too much attacking is just too much
Sort:
today i rolled out a challenge on live chess, and because my opponent was somewhat weak and because he made some very bad moves I thought to attack him and it all went terribly wrong and i had to resign in the end 
That's a shame: 31. Nc6+ instead of 31. Nb7+ and you would have won.
Asd others already pointed out, a little more concentration will definitely help:
