From your nickname and the way you play, we can assume that you are quite anxious!
Patience is the key in poker, there is no way around it if you want to improve!
You need to find ways to distract yourself while playing... (well... it works for me, to take your mind off the game, at least when making simple decisions).
Playing multiple games should also help you to get less bored.
I haven't played live poker for many years but I think if I tried to play nowadays, I would die of boredom.
Try doing other activities during your session like studying, watching gossip, the news, playing puzzles... It works for me, maybe it can work for you!
